The first output end of the first frequency hopping filtering module and the third output end of the second frequency hopping filtering module are electrically connected with the input end of the low-pass filter; the second output end of the first frequency hopping filtering module and the fourth output end of the second frequency hopping filtering module are electrically connected with the input end of the high-pass filter. The output end of the low-pass filter and the output end of the high-pass filter are electrically connected with an antenna; the first frequency hopping filtering module and the second frequency hopping filtering module are connected in a co-location control mode. The invention aims to provide an ultrashort wave frequency hopping combining module which has the advantages of simple structure, small insertion loss, large out-of-band rejection, high isolation, small volume, light weight and capability of high-speed frequency hopping switching.

Description

technical field [0001] The invention relates to the field of radio communication, in particular to an ultrashort wave frequency hopping combining module. Background technique [0002] Among the many electronic countermeasure technologies in the field of wireless communication, the frequency hopping electronic countermeasure combination technology is widely used in the radio frequency front-end electronic countermeasure frequency hopping channel of communication equipment. Multi-channel devices generally use a pair of antennas for multi-frequency transmission and reception. The combination technology currently in use generally uses a band-pass filter or a circulator for combination. Band-pass filter combination technology is to divide the working frequency band into several fixed band-pass frequency bands, and combine multiple filters together in a special way. This technology has low frequency band utilization, fixed channels that cannot be changed, and communication cannot ...

AI Technical Summary

Problems solved by technology

Band-pass filter combination technology is to divide the working frequency band into several fixed band-pass frequency bands, and combine multiple filters together in a special way. This technology has low frequency band utilization, fixed channels that cannot be changed, and communication cannot Disadvantages of high-speed hopping, the bandwidth of the circulator combination technology is relatively low, and can only be applied to fixed frequency points or narrowband communication systems

Both of the above two combining technologies have different shortcomings, and it is difficult to apply to modern digital frequency hopping communication systems
