Description
Technical Field
[0001] This invention relates to the field of radio communications, and more particularly to an ultra-shortwave frequency hopping combiner module. Background Technology
[0002] Among the many electronic countermeasures technologies in the field of wireless communication, frequency-hopping electronic countermeasures combining technology is widely used in the frequency-hopping channels of electronic countermeasures in the radio frequency front-end of communication equipment. Multi-channel devices generally share a single antenna for multi-frequency transmission and reception. Currently used combining technologies typically employ bandpass filters or circulators. Bandpass filter combining technology divides the operating frequency band into several fixed bandpass frequency bands and combines multiple filters together using a special method.

Circulator combining technology has relatively low bandwidth and can only be applied to fixed-frequency or narrowband communication systems.
