Amplifier Research 100A100

The Amplifier Research 100A100 is a solid-state, broadband RF power amplifier engineered for laboratory and field testing environments. Operating across 10 kHz to 100 MHz, it delivers 100 watts minimum linear output power and 150 watts saturated output, making it suitable for RF susceptibility testing, component characterization, wattmeter calibration, and driver applications for higher-power stages.

Technical Specifications

• Frequency Range: 10 kHz to 100 MHz


• Output Power: 100 watts (linear), 150 watts (saturated)


• Gain: 52 dB typical


• Noise Figure: 6 dB typical (above 1 MHz)
