The Model 240L is a broadband solid state power amplifier covering the frequency range of 20 kHz to MHz. More than 40W of RF power can be produced at the output, with low harmonic and intermodulation distortion. Up to 2Ö0W of saturated power can be produced with increased distortion products. A highly linear Class A design, the Model 240L will amplify inputs of AM, FM, SSB, pulse and other complex modulations. The 50 dB gain of the unit is unconditionally stable and will not oscillate for any possible combination of source and load impedance. It is protected against failure due to output load mismatch and/or overdrive. Output RF voltage level, as well as power output into 50 Ω, is monitored by a front panel meter. An integral power supply permits operation from 115/230 single phase AC power.
