MICROWAVE POWER LIMITER AND METHOD FOR ITS ASSEMBLING Russian patent published in 2008 - IPC H01P1/22 H01P1/10 

FIELD: superhigh-frequency radio engineering; diode-type power limiters; protection of radar receivers against impact of high-power microwave signal.

SUBSTANCE: diodes are disposed in two-step cylindrical package with insulating washings in each step to carry input and output transmission lines contacting internal conductor which is coaxial with respect to package through insulating bushings. Cooling ribs disposed on package provide for transferring heat from diodes in the course of device operation when high-level power is passed to input transmission line. Proposed method for assembling the limiter makes it possible to dispose internal conductor and diodes within package by means of auxiliary cylinders.

EFFECT: reduced level of microwave power arriving at radar receiving path down to value admissible at moment of high-power pulse radiation from home radars and its protection against asynchronous high-power radiation from outside radars.
