The BURLE 4662 PowerTube Linear Beam Power Tube datasheet provides electrical, mechanical specifications and application information.
The BURLE 4662 is a compact beam power tube intended for linear RF amplification in demanding environments. It can be used as a single‑sideband RF amplifier, oscillator, or anode‑modulated amplifier for Class C telegraphy and FM telephony, and it supports regulator and distributed‑amplifier configurations.
The datasheet lists detailed electrical ratings, mechanical dimensions, cooling requirements, and typical performance curves. It also references additional application guides for forced‑air cooling and screen‑grid considerations.
| CW Output Power | 300 W @470 MHz |
|---|---|
