Datasheet: Traveling Wave Tube - N20181

The N20181 from e2v is a broadband helix travelling wave tube. It is capable of providing a minimum of 100 W output power over the frequency band 4.5 – 18 GHz. Saturation gain is typically 40 dB.

The TWT incorporates a dual stage collector, providing high overall efficiency. The design also includes convergent electron gun incorporating a focus electrode grid switch that enables the TWT to be operated in either pulsed or CW mode, PPM focusing and conduction cooling.

The N20181 is small and lightweight. It has been designed to meet the most demanding environmental requirements.
