Chapter 1 Introduction
The 1140LA is a broadband solid state amplifier covering the frequency spectrum from 10
KHz to 2 MHz. It is rated at 1000 watts of RF power with low harmonic and
intermodulation distortion. Over 1500 watts of saturated power can be produced with
increased distortion products from 100 KHz to 2 MHz. A quasi linear Class AB design, the
1140LA will amplify inputs of AM, FM, SSB, pulse and any complex modulation signals.
The amplifier has 55 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 120/240 single phase AC power.
1.2 INSTRUMENTATION IDENTIFICATION
Each amplifier is identified by a serial number tag on the back panel of the unit. Both the
model number and the serial number should be quoted to identify specific unit.
