- Abstract
- In this study, a tunable bandpass filter with a hairpin line resonator and loading capacitors using varactor diodes was proposed. The filter was modified by adding varactor diodes to the coupling part to compensate for losses. The designed filter had a simple structure and the characteristics of wide tuning range of 87.9% from 430 to 1105 MHz and low insertion loss of less than 4.42 dB.
