Model TR 0.225-0.450-100 is a high power, transmit only, solid state RF amplifier that operates from 225 to 450 MHz minimum, and is packaged in an enclosure that is optimized for state-of-the-art military radio applications. This TR takes a 70 MHz IF input and performs a dual up-conversion to UHF. At the UHF RF frequency band, this power amplifier is employed in communication systems where high power, high efficiency, and high linearity are required. It transmits all the legacy waveforms and the newer WNW and SRW waveforms. All modes of WNW and SRW are compliant and utilized. The power added efficiency of the amplifier is typically 30 to 40 percent. Typical output power is 100W, but it is controllable in 1.0 dB increments or decrements. Power gain is -48 to 51 dB and VSWR is 2.0:1 maximum.
