| Abstract: | In order to meet the requirement of the signal conversion during the test of the airborne data link of UAV , we advance a tuning S-band double-way microwave conversion switch. The switch-control circuit choose the microwave signal amongSthe double ways. The two pectinate cavity filters loaded capacitance select available signals and get rid of unavailable signals, and the tuning bolts can realize same or different central syntonic frequency. The range of the tuning frequency can reach 20MHz. It is very flexible. This microwave conversion switch has the advantages of bigger power, lower insertion loss, high isolation, and easy-realized, can meet the electronic counter requirement of radar requirements. |
