CV2397 triode

This valve measures 60x18mm overall

This disc-seal valve will generate a maximum power output of 250mW at 5200MHz as an oscillator, and between 1 and 1.5W as an amplifier at 4000MHz with a drive of 0.25 to 0.5W

Heater voltage6.3V
Heater current500mA
Max pulse anode voltage1kV
Max CW anode voltage400V
Max mean anode dissipation *10W
Max mean anode current40mA
Amplification factor **65
Cag ***1.2pF
Cak ***0.03pF
Cgk ***3.6pF
Cgk (hot) *4.4pF

*: The electrodes must be cooled by conduction and the temperature of any glass to metal seal must not exceed 140°C
**: At Va=200, Ia=10mA
***: Measured with the valve cold

Referring to the photo, the discs are (top to bottom) anode, grid, cathode
