What is a Klystron Tube？

Klystron Definition

A Klystron is a vacuum tube used to amplify or oscillate microwave signals, important in various high-frequency applications.

Operating Principle

Klystrons work by modulating the velocity of an electron beam within a vacuum tube to generate microwave energy.

Applications

Klystrons are essential in devices like RADAR systems, radio receivers, and microwave transmitters.

Technical Specifications

Klystrons operate across a broad range of frequencies and power outputs, with efficiency levels suitable for specialized applications.
