| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| 8 GHz | 1980 V | — | — | — | 1 mA |
Application Notes
The grid should always be in cut-off condition when the high voltage is not applied. Overcurrent interlock should be provided to remove helix, collector and grid voltages if the helix current exceeds 5 mA.
