광대역 VHF 마이크로스트립 가변대역통과 여파기의 설계
Design of Wide Band VHF Microstrip Tunable Band-Pass Filters
초록
A new design method of microstrip wide band VHF tunable bandpass filters using varacter diodes is presented. In the proposed filter both the input and output ports are coupled through capacitors, and an open micro-strip line is inserted between the coupled line in order to obtain the desired degree of coupling. The optimized filter responseses for the frequency range of 220-404MHz by TOUCH-STONE are compared with the measured ones.
