Abstract

The invention relates to a V-waveband and high-power frequency hopping colocation filter. The V-waveband and high-power frequency hopping colocation filter comprises a logic control unit 1, a switch drive unit 2 and a comprehensive radio frequency turning unit 3 which are combined to form a whole, wherein a memory module U1 and an external debugging data interface J2 of the logic control unit 1 can output control signals to ten ways of drive circuits of the switch drive unit 2 through an electronic switch module; the comprehensive radio frequency tuning unit 3 comprises ten ways of resonant circuits, and each way adopts a parallel resonance circuit and performs inductive coupling on an air core inductance cross coupling structure through an earth shaft, so that different sub-filters have the same relative bandwidth; and values of different capacitors in each way of parallel resonance circuit correspond to different sub-filter center frequency, and the number of sub-filters is 210. The V-waveband and high-power frequency hopping colocation filter has the advantages of high frequency hopping speed, small insertion loss, good standing wave performance, capacity of being used in a 100 W high-power occasion and the like.

Description

technical field [0001] The invention relates to a co-site filter, in particular to a V-band high-power frequency-hopping co-site filter. Background technique [0002] Nowadays, frequency hopping technology is one of the main anti-jamming means in wireless communication, and frequency hopping filter is used as the filter device at the terminal of the transmitting system and the preselection device at the front end of the receiving system, and its performance directly affects the quality of the sending and receiving signals in the system. Since the center frequency of the frequency hopping filter changes with the channel frequency hopping frequency, it can improve the anti-blocking and anti-out-of-band interference performance of the communication system, thereby improving the comprehensive anti-interference ability and networking ability of the system. [0003] As the co-location of multiple frequency hopping radio stations is becoming more and more common, in order to reduce...
