Abstract

A new filter construction is proposed to realize a highly miniaturized microwave bandpass filter. An element of resonator filter is composed of a square dielectric post and a round inner conductor. Each element of resonator is located in a housing similar to a conventional combline filter; however, the length of a resonator is basically a quarter wavelength. The higher unloaded Q and a larger inter-resonator coupling were implemented through two factors: open-boundary condition on the periphery along the dielectric post and the air spacing between resonators. Five-stage Chebyshev response bandpass filters were developed at 800 MHz to have 20 approximately equals 30 MHz passband and 0. 8 approximately equals 1. 0 db insertion loss at the temperature range: minus 35 approximately equals plus 80 degree C. The volume and the weight of the filters are about 25 cm**3 and 60 g respectively.
