Power - Tetrode (NOT beam) (over 1000V 100W) ·Tetrode

ZP1015

Heat-sink and forced-air-cooled L-band tetrode for pulsed RF amplifier or oscillator service. Its ratings emphasize high peak microwave output, with multi-kilovolt plate operation and short pulse capability rather than continuous-wave transmitter duty.
