Description

The Eimac 4K3CB is an air cooled, permanent magnet focused, power amplifier kly~ stron. It will deliver a minimum CW output power of one kilowatt at frequencies from 4.4 to 5.0 kMc, with a minimum power gain of 43 db. The 4K3CB is designed for use in transmitters where compactness and light weight are essential.
