The E&I 240L is a broadband solid state amplifier covering the frequency spectrum from 10 kHz to 12 MHz. It is rated at 40 watts of RF power with low harmonic and intermodulation distortion. Over 100 watts of saturated power can be produced with increased distortion products. A highly linear Class A design, the 240L 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. RMS forward and reverse powers are monitored by a front panel meter. An integral power supply permits operation from 115/230 single-phase AC power. The E&I 240L produces rated power output at its output connector, regardless of load impedance. Any power reflected due to output load mismatch is absorbed in the amplifier. Therefore, although the output impedance is 50 ohms (maximum VSWR: 2:1), the amplifier will work into any load impedance.
