The Amplifier Research 700A1 is a solid-state, broadband RF power amplifier engineered to deliver high-power output across extended frequency ranges with built-in protection and precision measurement. This self-contained amplifier combines 700 watts minimum output capability with integrated safeguards against excessive VSWR, high line current, over-temperature conditions, and excessive output power. The unit employs time-delay and zero-crossing turn-on circuitry to minimize inrush current and extend component longevity.
