Abstract: Based on the guided tracking interference of high-speed frequency hopping signals, through the analysis on the distance and time of frequency hopping signal, a tunable broadband follower jamming receiver is designed for HaveQuick (HQ), which has fixed frequency, high-speed frequency hopping, single and multi network station, the receiver has both simplex and duplex working modes. In order to enhance the effective power of interference transmission and and meet the requirements of fast switching between multiple frequency bands, the receiver adopts a high linear narrowband tunable filter, the tunable filter uses 8 bit tuning capacitors with a 3 dB relative bandwidth of 1%, the rejection of center frequency out of 10% reaches 46 dBc, the input P_-1 is greater than 29 dBm, and the frequency hopping time is only 4 μs. Experimental testing shows that when the communication station is at 5 km, it can achieve tracking interference within 10 km.
