High performance single-supply 300MHz devices drive video signals on 75-ohm lines at close to zero volts

GENEVA, March 9 / — STMicroelectronics (NYSE:STM), a world leader in analog ICs, today announced the introduction of two new 300MHz amplifiers designed to drive very high-definition signals on 75-ohm video lines in high-end industrial and medical imaging systems, and in HDTV-enabled set-top boxes and DVD players. The cost-effective TSH340 and TSH341 video amplifiers feature operation on a single 3V to 5V single power supply, with the capability to drive the video signal very close to zero volts.

The TSH340 is a buffer with internal gain, providing savings both on board space and in the number of components; the gain is set at 6dB to allow the right level of video signal while maintaining good line matching. The TSH341 is an op-amp that uses the same voltage feedback architecture as the TSH340, but allows the gain to be set externally. Both use a very high-speed 0.25-micron complementary manufacturing technology to achieve up to 300MHz bandwidth for only 9.8mA quiescent current.

High slew rates, low distortion and a gain flatness of 65MHz, combined with a low input-voltage noise of 7nV/sqrtHz, make the TSH340 and TSH341 devices an excellent choice to drive DAC outputs on 75-ohm video lines. The amplifiers are input/output negative rail, which allows them to drive the signal to within 60mV of ground — guaranteed by production testing — while operating on a single 5V supply, and enables the video signal to be driven directly from the DAC output without any transition capacitance.

The use of a single power supply, eliminating the need for the negative supply that is usually required, reduces the complexity of applications using the devices and so reduces costs. These are essential and easy-to-use components for high performance video equipment demanding wide bandwidth and high signal purity. The amplifiers are specified for both 150-ohm and 100-ohm loads, and are supplied in the tiny SOT23-5 and SO8 plastic packages.

The TSH340 and TSH341 video amplifiers are supported by an evaluation board kit, optimized for high-speed operational amplifiers, which includes a CD-ROM containing datasheets, application notes, articles and a user manual. They are available in volume now at a price of $1.50 for quantities of 5,000.

National’s New LM3200 Is the First in a Revolutionary Family of Analog DC-DC Converters Optimized to Save Power and Reduce Board Space in Smart Phones, Wireless LANS, PDAs and Other Portable Wireless Devices

SANTA CLARA, Calif. and MUNICH, Germany, Nov. 9 - National Semiconductor Corporation (NYSE:NSM) today announced a new family of DC-DC converters optimized for powering radiofrequency (RF) power amplifiers from a single lithium-ion battery. These new chips from National will enable cell phone makers to reduce power consumption by up to 80 percent, while increasing talk time as much as 90 minutes. The first cell phones to use National’s new LM3200 DC-DC converters will appear in the market by year-end.

With 2.5G and 3G wireless handsets gaining popularity, cell phones are becoming a one-stop multimedia station with features such as text messaging, email and software downloads. These new handsets require higher transmit-and-receive rates for (RF) power amplifiers, which mean that they consume more power. Because the RF power amplifier consumes 40 to 60 percent of the overall power budget, reduction of its power consumption will provide a significant increase in the battery life of a handset.

National’s new LM3200 is designed specifically to power RF power amplifiers. Compared with previous step-down switchers, the LM3200 has a high switching frequency that allows it to use small external components such as a 2.2 uH inductor. The LM3200 also has an analog voltage-control input that dynamically controls the output voltage of the device depending on the power requirements of the power amplifier. Its bypass operation allows it to support the power amplifier’s power requirement during peak usage periods to keep the phone running longer. The converter steps down an input voltage from 2.7V to 5.5V to a variable output voltage from 0.8V to 3.6V, while output voltage is set using a voltage-control analog input for adjusting power levels and efficiency of the RF power amplifier.

“With these new products, National is targeting the power amplifier — a previously unregulated portion of the cell phone — to enable dramatic improvements in battery life and talk time,” said Peter Henry, vice president of National Semiconductor’s Portable Power Products Group. “National’s LM3200 features a small-size chip-scale package, high switching frequencies and compatibility with a wide variety of industry-standard platform reference designs that will enable our customers to offer phones and other portable devices with outstanding performance.”

Key Technical Specifications of National’s New LM3200

The LM3200 offers four modes for mobile phones and similar RF PA applications. Fixed-frequency pulse-width modulator (PWM) mode minimizes RF interference and provides efficient performance under typical operating conditions. Forced bypass mode turns on an internal bypass switch to power the PA directly from the battery. Automatic bypass mode minimizes dropout by turning on the bypass switch when the battery decays close to the output voltage. Shutdown mode turns the device off and reduces battery consumption to 0.1uA (typ.). The LM3200 is designed on National’s CMOS7 process, built at National’s plant in South Portland, Maine, and tested and assembled at the company’s facility in Melaka, Malaysia.

National’s LM3200 is available in a 10-pin lead-free micro SMD that measures only 2.2 mm by 1.8mm. A high switching frequency (2MHz) allows use of tiny surface-mount components. Only three external components, a 2.2uH inductor and two 10uF ceramic capacitors, are needed to complete the application circuit. National’s LM3200 is priced at $1.60 each in quantities of 1,000 pieces.

The figure shows one of four solid-state power amplifiers, each capable of generating an output power > or =240 mW over one of four overlapping frequency bands from 71 to 106 GHz. (The bands are 71 to 84, 80 to 92, 88 to 99, and 89 to 106 GHz.) The amplifiers are designed for optimum performance at a temperature of 130 K. These amplifiers were developed specifically for incorporation into frequency-multiplier chains in local oscillators in a low-noise, far-infrared receiving instrument to be launched into outer space to make astrophysical observations. The designs of these amplifiers may also be of interest to designers and manufacturers of terrestrial W-band communication and radar systems.

Each amplifier includes a set of six high-electron-mobility transistor (HEMT) GaAs monolithic microwave integrated-circuit (MMIC) chips, microstrip cavities, and other components packaged in a housing made from A-40 silicon-aluminum alloy. This alloy was chosen because, for the original intended spacecraft application, it offers an acceptable compromise among the partially competing requirements for high thermal conductivity, low mass, and low thermal expansion. Problems that were solved in designing the amplifiers included designing connectors and packages to fit the available space; designing microstrip signal-power splitters and combiners; matching of impedances across the frequency bands; matching of the electrical characteristics of those chips installed in parallel power-combining arms; control and levelling of output power across the bands; and designing the MMICs, microstrips, and microstrip cavities to suppress tendencies toward oscillation in several modes, both inside and outside the desired frequency bands.

Canada-based Unity Wireless Corporation announced it has commenced shipments in the framework of its first RF (radio frequency) power amplifier supply agreement with one of China’s largest builders of CDMA and GSM repeater systems.

The Company did not name the customer, but revealed that it employs 200 people in 8 offices, has relationships with OEM (Original Equipment Manufacturer) wireless infrastructure equipment vendors in China and provides network installation services to China’s wireless service providers.

The initial order is valued at US$186,500. Unity began shipping the order in December 2001, and the final deliveries are scheduled to be shipped in January 2002.

RF power amplifiers delivered under the supply agreement are required to meet the specification under the Customer’s repeater supply contract with China Unicom and are anticipated to be used in Unicom’s national CDMA wireless telecommunications network build- out.

“We believe that this agreement is very significant given that it is our first in China and the Customer is an OEM supplier to some of China’s largest domestic infrastructure suppliers including ZTE Corporation and Shanghai Datang,” commented Dave Orton, Unity Wireless Corporation’s VP of Corporate Marketing and leader of the Asian sales effort.

Designed to add power instead of replacing power, Scalable Power amplifiers can be combined, divided, and controlled by central location via amplifier controller. Amplifiers can be upgraded to total of 4 like devices to be used as one unit, or separated to function independently. Controller also allows for power to be divided; when allotted amount of watts are not needed, each independent amplifier can function separately at multiple locations.

Power Can Be Expanded Or Divided With The Use Of A Controller

Souderton, PA - 5/10/06 - As RF test levels and test distances continue to increase, many test labs are forced to replace smaller amplifiers with larger, more powerful models. AR Worldwide RF Microwave Instrumentation believes there’s a better, more cost-efficient way to meet changing needs.

The company’s new Scalable Power offering makes it possible to add power instead of simply replacing power. It also enables users to divide the power by splitting amplifiers for multiple uses, thereby dramatically increasing the flexibility of its amplifiers.

The heart of this scalable power technology is the controller. It allows multiple amplifiers to be combined and controlled by a central location.

For example, a 200S1G4A amplifier (200 Watts / 0.8-4.2 GHz) can be purchased today; and when specs change and more power is required, another 200S1G4A amplifier can be added, along with a controller, to make a 400S1G4 amplifier (400 Watts / 0.8-4.2 GHz). The two amplifiers can be separated and function independently or brought together and used as one 400S1G4. This system can be upgraded to a total of four independent 200S1G4A amplifiers that can be combined for 700 watts. A variety of AR Worldwide amplifiers can be used as the building blocks for Scalable Power. Each can be combined with up to four of the same model amplifiers to increase power as needed.

The Scalable Power offering also allows for power to be divided. For example, a 3000W1000 amplifier can be purchased to provide 3000 watts of power. When 3000 watts are not needed, each of the three 1000W1000C independent amplifiers can function separately for 1000 watts at multiple locations.

The flexibility of the new Scalable Power offering represents AR Worldwide’s commitment to meeting the changing needs of the market and providing its customers with a powerful competitive edge.

ntegrating precision gain-setting resistors on-chip, Model LT6402 and LT6411 differential amplifiers can be used as high-speed ADC drivers, twisted-pair line drivers, and single-ended to differential signal converters. Model LT6402 has -3 dB bandwidth of 300 MHz, and is available in 6, 12, and 20 dB fixed gain options. With -3 dB bandwidth of 650 MHz and slew rate of 3,300 V/[micro]s, Model LT6411 dual-selectable gain amplifier has supply range of [+ or -]2.25V to [+ or -]6.3V.

MILPITAS, CA - November 14, 2006 - Linear Technology Corporation introduces the LT6402 and LT6411, two new differential amplifiers suitable as high-speed ADC drivers, twisted-pair line drivers and single-ended to differential signal converters. These new products utilize a novel design topology to integrate precision gain-setting resistors on-chip. In addition to simplifying system design and reducing external component count, these devices optimize distortion power and noise performance, critical for high-speed communications applications. With a -3dB bandwidth of 300MHz, the LT6402 is available in three fixed gain options, 6dB, 12dB, and 20dB. Exceptionally low noise and low distortion make the LT6402 ideal for communications transceiver applications as a differential 12- to 14-bit ADC driver, a general-purpose differential gain block, or in other applications requiring differential drive. The LT6402 further minimizes external circuitry and simplifies design by providing an on-chip filter and an output common mode voltage pin (VOCM).

The LT6411 is a dual-selectable gain amplifier that can be configured to drive differential signals. The gain of each amplifier can be independently selected, resulting in differential gains of -1, +1, and +2 (0dB or 6dB). With a -3dB bandwidth of 650MHz and a slew rate of 3300V/[micro]s, the LT6411 achieves very low distortion for input signals up to 70MHz, while consuming only 16mA supply current. During periods of inactivity, the LT6411 can be disabled, dropping current consumption to less than 0.35mA max per amplifier. The LT6411 can be used on split supplies as large as [+ or -]6.3V or on a single supply as low as 4.5V.

“The new LT6411 and LT6402 provide system designers with the flexibility and performance they need to drive high-speed communications and video signals in a wide range of applications,” says Brian Black, product marketing manager for Linear Technology’s Signal Conditioning product group. “These devices are well suited for driving high-speed ADCs such as Linear Technology’s 14-bit 80Msps LTC2249.”

The MAAPSS0104 is designed to have a linear gain of 32 dB, operate over the 3.3 GHz - 3.8 GHz frequency range, and achieve 26 dBm linear output power with EVM <2.5% at 5V.

Both amplifiers are optimized to achieve high power added efficiency (PAE) while maintaining high linear output power (OFDM, QAM-64, 54Mbps) with an EVM <2.5% at 26 dBm. Both products are designed to generate 26 dBm of linear output power (OFDM, QAM-64, 54Mbps), while drawing 600 mA of current and maintaining an EVM of <2.5% at 5V operation. The small signal operating current is only 250 mA, which is required to maintain high efficiency for thermal and power sensitive systems.

M/A-COM’s MAAPSS0103 and MAAPSS0104 are three-stage power amplifiers designed specifically for linear 802.16d applications and are available in a RoHS-compliant 4mm 16-lead PQFN plastic package. The amplifiers feature an integrated detector for accurate power control and a separate power mode pin for current savings in a shutdown mode state.
