Design and performance of monolythic waveguide dielectric filters are discussed. To obtain high accuracy of synthesis technique the analytical approach and non-linear optimization have been done successfully. Some results of practical realization of given filters on the basis of integrated waveguide technology are presented.
Magnetic tunable microwave band-pass filters on the basis of ferrite loaded resonators (FLR) have been considered. The field model of coupled FLR is suggested taking into account the particular conditions of excitation. The behavior of coupling coefficient and external Q are studied for various electrical and geometrical parameters of FLR on the resonance frequencies of principal mode for a particular rectangular waveguide. The experimental results showed a good agreement with theoretical results.
