<p>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 optimised by applying electromagnetic simulation of a full filter response. Other dimensions of the puck may also be optimised. If two or more pucks are present in the cavity, the inter-puck spacing is also optimised. <IMAGE></p> |
