The 75A2 is a broadband solid state amplifier system covering the frequency spectrum from 300 KHz to 35 MHz. Each channel is rated at 75 watts of RF power with low harmonic and intermodulation distortion. Over 125 watts of saturated power can be produced with increased distortion products. A highly linear Class A design, the 75A2 will amplify inputs of AM, FM, SSB, pulse and any complex modulation signals. The amplifier has 50 dB gain it is unconditionally stable and will not oscillate even with combinations of mismatched source and load impedance. It is protected against failure due to output load mismatch and/or overdrive.
