Toshiba America Electronic Components: Power-added amplifiers claim improved power efficiency

Aiming at microwave-digital radios and block-up converters, the X-band GaAs FETs support point-to-point and point-to-multipoint terrestrial communications. Operating over a 10.7- to 11.7-GHz range, the TIM1011-2UL and the TIM1011-8UL provide 36 and 39% power-added efficiency, respectively. The TIM1011-2UL has a typical output power of 2W or 33.5 dBm at a 1-dB-gain-compression point. The TIM1011-8UL has a typical output power of 8W or 39.5 dBm at a 1-dB-gain-compression point and 9-dB typical linear gain. Targeting satellite applications, the TIM5964-30UL and the TIM7785-30UL 30W C-band power amplifiers operate over 5.9- to 6.4- and 7.7- to 8.5-GHz frequency ranges, respectively. These devices suit use in block-up-converter applications for small-aperture terminals and solid-state power amplifiers. The TIM5964-30UL has a typical output power of 45 dBm at 1-dB-gain-compression and a 10-dB typical gain. The TIM7785-30UL features an output power at 1-dB gain-compression-point of 45 dBm typical and a 9-dB typical gain. The TIM5964-30UL and the TIM7785-30UL amplifiers provide a 41 and 39% power efficiencies, respectively. The TIM1011-2UL and the TIM1011-8UL X-band devices cost $217.50 and $405, respectively; the TIM5964-30UL and the TIM7785-30UL C-band amplifiers cost $450 and $742.50, respectively.
