The ENI 3200L RF Amplifier covers the frequency range of 250 kHz to 150 MHz, with Class A linear power output ranging from 25 to 200 Watts. This reliable solid state unit is primarily designed for HF and VHF transmitters, RFT/EMI testing, nuclear accelerators, plasma equipment, and other VHF applications.

The ENI 3200L features complete stability and absolute protection against overdrive and overload. The ENI 3200L will amplify inputs of AM, FM, SSB, TV, and other complex modulations limited only by their peak input and bandwidth. Both output RF voltage level and power output into the load are accurately monitored by a built-in front panel meter. Each amplifier is equipped with a regulated power supply and forced-air cooling system.

Conservative, solid state design reduces size and weight and simplifies maintenance and service. ENI's unique hybrid combining of power amplifier modules effectively prevents a total loss of power by coupling the outputs of a number of transistors to produce the total output. Should any individual transistor fail to operate, the amplifier will continue to operate at reduced power.
