| Abstract: | The design of electric tunable broadband comb line filter is introduced in the paper. Using four order varactor loaded terminal short circuit,filter input is equipped with single stage self-bias circuit. Within the zone,ups and downs is small. Loss is small in low frequency. Test shows its working frequency range of 668.6 MHz~1300 MHz,insertion loss of less than 6 dB,3 dB bandwidth less than 5%and resistance's suppression ratio for 45 dB with rectangular factor of 5. |
