The Amplifier Research 300A100 is a solid-state broadband amplifier delivering 300 watts CW linear power output across 10 kHz to 100 MHz instantaneously. Operating with less than 1.0 dB gain compression and a minimum 55.5 dB gain, this amplifier maintains ±1.5 dB flatness (±0.5 dB with internal leveling) across its full frequency range. The unit accepts 1.0 milliwatt maximum input to achieve rated output.
