The Model A-150 is a completely solid state RF power amplifier, capable of providing more than 150 W of linear power and up to 250 W of CW and pulse power from ,3 to 35 MHz. The Amplifier operates over its entire frequency range without bandswitching or other adjustments. A highly linear class A design, the Model A-150 will amplify of AM, FM, SSB, pulse and other complex modulations with minimum distortion. Flat gain response permits the unit to be driven to its full power output by virtually all commercial signal and sweep generators. Although most power amplifiers are designed to deliver their rated power into a matched load, their mismatch. The Model A-150 is designed to provide a constant forward power, regardless of output load mismatch. The Model A-150 is designed to provide a constant forward power, regardless of output load impedance. Power reflected due to mismatch is absorbed in the unit’s output circuitry. Output RF voltage level as well as power into 50Ω is monitored by a front panel meter. An integral Power Supply permits operation directly from the AC line.
