Abstract

The realisation of a band-pass sixth-order elliptic filter using two triple-mode dielectric-loaded cylindrical cavities is described. In this filter the degenerate modes are two orthogonal hybrid (HE₁₂₁) modes and one TM₀₂₁ mode. Compared to a similar filter designed with empty cavities, the developed filter is approximately six times smaller in volume and three times lighter in weight. Data on degenerate modes and on coupling coefficients are generated by a computer program developed for the analysis of cylindrical cavities axisymmetrically loaded with dielectrics.
