Toshiba Expands GaAs FETS Lineup With Four Power Added Amplifiers Optimized for Power Efficiency

IRVINE, Calif., June 16 /PRNewswire/ -- Toshiba America Electronic Components, Inc. (TAEC*) announced the expansion of its gallium arsenide field effect transistor (GaAs FETs) lineup with four new devices optimized for power efficiency. The Power Added Efficiency enhanced GaAs FETs, developed by Toshiba Corp. (Toshiba), are targeted for microwave radios and block up converters (BUCs) and will be exhibited in TAEC's booth, #1701, at the 2008 IEEE MTT-S International Microwave Symposium, which will be held June 15 through 20 in Atlanta, Georgia.

Two new X-band GaAs FETs for microwave digital radios supporting point-to- point and point-to-multipoint terrestrial communications, the TIM1011-2UL and the TIM1011-8UL, operate in the 10.7 to 11.7 GHz(1) range. The TIM1011-2UL has an output power at one-dB gain compression point of 2W, or 33.5dBm (typ.), linear gain of 9.5dB (typ.) and power added efficiency of 36 percent. The TIM1011-8UL features an output power at one-dB gain compression point of 8W, or 39.5dBm (typ.), linear gain of 9.0dB (typ.), and power efficiency of 39 percent.

For satellite applications, Toshiba has added two 30W C-band power amplifiers that operate in the 5.9 to 6.4 GHz and 7.7 to 8.5 GHz range. Both are targeted for use in BUC applications for very small aperture terminals (VSAT) and solid-state power amplifiers (SSPAs). The TIM5964-30UL has an output power at one-dB gain compression point of 45dBm (typ.), gain of 10dB (typ.) and power efficiency of 41 percent. The TIM7785-30UL features an output power at one-dB gain compression point of 45dBm (typ.), gain of 9dB (typ.) and power efficiency of 39 percent.

"In the conversion from old analog transmission technology to digital in the telecommunication industry, system operators need to install more equipment or boards into the same limited space, and are asking microwave communication system designers to develop smaller and lighter systems. The improved efficiency of these power amplifiers will help microwave designers ease thermal management in their BUC and SSPA designs such as smaller heat sinks and possible fan-less configurations contributing to reduced size and weight of the overall system," said Homayoun Ghani, business development manager, Microwave, Logic, and Small Signal Devices, in TAEC's Discrete Business Unit. "In addition, Toshiba is also developing high gain and high Power Added Efficiency FETs for Ku-band to address to SATCOM market."
