PLASTIC RESONATOR SUPPORT AND RESONATOR TUNING ASSEMBLY

摘要

A filter (401) includes a cavity, a resonator structure, and a plastic resonator support (201) and further may include a plastic tuning assembly suitable for both manual and automatic tuning. The dielectric resonator structure comprises a substantially cylindrical ceramic resonator (101), and a plastic support (201) having a plurality of spaced apart elements diverging from a shoulder of the plastic support, each of the elements terminating in a cantilevered stop (203), the cantilevered stops holding the ceramic resonator (101) in a fixed relationship with respect to the plastic support (201) and the cavity.
