Single Band Amplifiers
Models 15S1G6 and 50S1G6 are single band amplifiers that cover the 1 to 6 GHz frequency band. Solid-state, 1 to 6 GHz amplifiers are not unusual, but they all require dual bands (two separate amplifiers) to provide high output power and good gain flatness to provide one with a useable instrument. That is, until AR RF/Microwave Instrumentation created these single band models. They provide 15 and 50 W of linear output power with excellent gain flatness.
