Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Pulse Oscillator (3000 MHz) | 6000 V | 25000 | 2800 | 70 | 6000 mA |
| Pulse Oscillator (Heater 7.0 V) | 6000 V | 25000 | 2800 | 70 | 12000 mA |
Application Notes
In high frequency operation, back bombardment raises cathode temperature. After adjustment, heater voltage must be reduced to prevent overheating. Cooling air flow must continue for 2 minutes after power down.
