AI Technical Summary

Technical Problem

Existing receiver protectors suffer from problems such as low power tolerance, long recovery time, large size, or high production cost.

Method used

Employing a klystron structure, the electromagnetic wave carrying the signal is input into the output cavity through the input cavity, causing the electromagnetic wave to interact with the electron beam. This achieves signal amplification at low power and signal attenuation at high power, avoiding the use of a heavy magnet structure.

Benefits of technology

It improves power tolerance, shortens recovery time, reduces size and production costs, and improves production consistency.

Abstract

The invention discloses a receiver protector based on a klystron, which realizes the working characteristics of the protector of normal amplification under low-power input and signal attenuation under high-power input by utilizing the characteristic that electromagnetic waves under different input powers and electron beams in a drift tube generate different degrees of beam-wave interaction. The receiver protector provided by the invention keeps the advantage of high tolerance power of a vacuum electronic device protector, the recovery time is reduced, and the receiver protector provided by the invention is small in size, low in cost and high in reliability compared with a common vacuum electronic device due to the non-magnetic structure. And the production consistency of the product is also improved due to the elimination of the magnet material with individual difference.
