Abstract
The dimensions of a resonator filter comprising at least one puck (12, 14) in a metal cavity (16) are calculated by deriving the diameter c and thickness j of the puck, the spacing of the puck from the cavity walls by a mode-matching technique, then optimized by applying electromagnetic simulation of a full filter response. Other dimensions of the puck may also be optimized. If two or more pucks are present in the cavity, the inter-puck spacing is also optimized.
