Description
technical field [0001] The invention relates to the technology of electronic components, in particular to the technology of a micro-power frequency hopping filter. Background technique [0002] Frequency hopping filters are indispensable components in large-scale communication systems. They are mainly used to solve electromagnetic compatibility problems caused by simultaneous communication of multiple frequency hopping communication devices. They are more flexible than fixed-frequency band-pass filters and can be used in the same Increased capacity several times under the condition of bandwidth can especially expand the communication capacity of large aircraft platforms in my country from the current 4 to 5 anti-jamming stations to 20 stations, which has important economic and social value. Handheld communication devices play an important role in modern warfare. Handheld devices with lightweight digitalization, low power consumption, wide frequency band, and fast frequency ho...
