9 kHz to 250 kHz Power Amplifier, 1100 Watts
The 1140LA is a broadband solid state amplifier covering the frequency spectrum from 9 kHz to 250 kHz. It is rated at 1100 Watts of RF power with low harmonic and intermodulation distortion. Over 1500 watts of staturated power can be produced with increased distortion products from 100 KHz to 2 MHz. A quasi linear Class AB design, the ENI / E&I 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 115/230 single phase AC power.
ENI / E&I 1140LA Features:
- Load Power Measurement
- Solid State Reliability
- Forced Air Cooling
