Typical Operation
| Mode | Plate V | Gm (µmhos) | Rp (Ω) | µ | Plate mA |
|---|---|---|---|---|---|
| Class A Amplifier (Per Section) | 100 V | 4000 | 15000 | 60 | 3.7 mA |
| Class A Amplifier (Per Section) | 250 V | 5600 | 10900 | 60 | 10 mA |
Application Notes
Especially suited for industrial and military airborne equipment. High ratio of plate current to transconductance makes it adaptable for combined high frequency oscillator and mixer, or grounded grid RF amplifier.
