Toshiba Expands C-Band GaAs FETs Lineup With Three Power Amplifiers Optimized For Power Added Efficiency

IRVINE, Calif., June 9 /PRNewswire/ -- High Power Added Efficiency Lineup Includes GaAs Amplifiers with Higher Gain for Microwave Radios and SSPAs

IRVINE, Calif., June 9 /PRNewswire/ -- Toshiba America Electronic Components, Inc. (TAEC*) and its parent company, Toshiba Corp., announced the expansion of its gallium arsenide field effect transistor (GaAs FETs) lineup with three new devices optimized for power efficiency. The Power Added Efficiency enhanced GaAs FETs are targeted for microwave radios and solid-state power amplifiers (SSPAs) and will be exhibited in TAEC's booth, #623, at the 2009 IEEE MTT-S International Microwave Symposium, which will be held June 7 through 12 in Boston, Massachusetts.

Two new Extended C-Band GaAs FETs for microwave digital radios supporting point-to-point and point-to-multipoint terrestrial communications, the TIM5867-8UL and the TIM5867-30UL, operate in the 5.85 to 6.75 GHz(1) range. The TIM5867-8UL has an output power at 1dB gain compression point of 8W, or 39.5dBm (typ.), linear gain of 10.0dB (typ.) and power added efficiency of 36 percent. The TIM5867-30UL features an output power at 1dB gain compression point of 30W, or 45.0dBm (typ.), linear gain of 10.0dB (typ.), and power efficiency of 41 percent.

For satellite solid-state power amplifier (SSPA) applications, Toshiba has added a 60W C-band power amplifier that operates in the 7.7 to 8.5 GHz range, with higher gain. The TIM7785-60UL has an output power at one-dB gain compression point of 48dBm (typ.), gain of 7.5dB (typ.) and power efficiency of 36 percent.

"Toshiba has a broad power GaAs FET product family to support extended C-band, but many customers have asked us to upgrade the family using the latest process technology. High gain and high power added efficiency features will help designers build energy-efficient microwave radios," said Homayoun Ghani, business development manager, Microwave, Logic, and Small Signal Devices, in TAEC's Discrete Business Unit. "One of the design challenges with 7 to 8GHz SSPAs has traditionally been that they sometimes have a lower device gain compared to 5 to 6GHz parts, so designers could not use the same lineup for 7 to 8GHz power amplifiers as they do for lower frequency amplifiers. The TIM7785-60UL, 60W Power GaAs FET offers 7.5dB of G1dB, which is a 1.5dB improvement over Toshiba's previous 60W product in that band. The improved gain will help microwave designers reduce the number of parts in their overall system."
