Modelling and experimental research of filter onhalf-wave resonators with quarter-wavelength links was made. The following experimental result were received: - center frequency was 3.7 GHz; - passband width was 230 MHz; - losses in the passband were not more than 4 dB; - bkocking at tuning ± 200 MHz was not less than 40 dB. It is recommended to use the filter in a microwave receiver input circuit.
