Toptek Communications PA-80U UHF Power Amplifiers are efficient and wideband capable for FM, SSB, CW and Digital modes of operation. They offer a nominal output of 80 watts output with 3 to 5 watts input drive on any frequency from 430 to 470 MHz. To accommodate duplexer or antenna ratings, power output maximum can be preset to one of eight steps: 10W, 20W, 30W, 40W, 50W, 60W, 70W, 80W. An attractive and useful front panel and heatsink chassis gives these amps everything they need for commercial and Amateur UHF operations.
