The ENI 1140LA is a robust solid-state RF power amplifier designed for high-power laboratory and industrial applications. Operating over a frequency range of 9 kHz to 250 kHz, it delivers a nominal output of 1100 Watts with 55 dB of gain. Featuring Class B operation, a built-in analog power meter, and forced-air cooling, it is engineered to withstand severe load mismatches (any VSWR) without damage.
