325LA Datasheet

The ENI / E&I 325LA solid state amplifier is primarily designed for HF and VHF transmitters, RFI/EMI testing, nuclear accelerators, plasma equipment, and other VHF applications.

Featuring complete stability and absolute protection against overdrive and overload, the 325LA 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.
