GI-46B Pulse Generator Triode Tube
NOS  in original BOX
SAME DATE

Generation, amplification of HF oscillations in pulsed operating modes with output power per pulse up to 30 kW

The GI-46B pulse generator triode in ceramic-metal design with forced air cooling for operation in the decimeter frequency range.
Designed to generate and amplify high-frequency oscillations in continuous and pulsed operating modes in the range from 300 to 1050 MHz with an output power per pulse up to 30 kW with anode modulation.
The GI-46B triode is used for operation in self-excited generators and amplifiers.
Forced air cooling not less than 24 m3/h
