Abstract
A cavity filter has a resonator. The resonator is engaged by a rod having a mounting portion and a thermal dissipation portion. The mounting portion of the rod extends through the floor of the cavity filter to engage an internal surface of the resonator. The thermal dissipation portion dissipates heat from the resonator to the outside of the cavity filter.

A cavity filter having a cavity formed by a floor, at least one wall, and a top, comprising:
- a resonator within the cavity having an interior surface and an exterior surface;
- and
- a rod having a mounting portion and a thermal dissipation portion;
- wherein the mounting portion of the rod extends through the floor of the cavity to engage the interior surface of the resonator and the thermal dissipation portion of the rod extends outside the cavity.
An apparatus for mounting a resonator within a cavity filter having a cavity formed by a floor, at least one wall, and a top, comprising:
- a thermal dissipation portion;
- and
- a mounting portion extending through the floor of the cavity;
- wherein the mounting portion engages an interior surface of the resonator and the thermal dissipation portion extends outside the cavity.
A method for dissipating heat from a resonator within a cavity filter, the cavity filter having a cavity formed by a floor, at least one wall, and a top, the method comprising:
- extending a mounting portion of a rod through the floor of the cavity filter;
- engaging an interior surface of the resonator with the mounting portion;
- and
- dissipating heat through a thermal dissipation portion of the rod outside the cavity.
