Abstract
In one embodiment, the cavity filter includes a housing defining a cavity, and at least one post projecting from a first interior surface of the housing towards a second interior surface of the housing. The first interior surface faces the second interior surface. The cavity filter further includes a thermo electric cooler disposed on the housing. The thermo electric cooler is configured to one of cool and heat at least a portion of the housing.
Claims23
A cavity filter, comprising:
- a housing defining a cavity, the housing including a bottom, at least one side wall and a cover, the bottom including a base having a first surface and an opposite second surface, the first surface being plated in a first conductive material, at least a portion of the first surface being a first interior surface of the housing, the bottom including first and second apertures, a first conductive strip being formed on the second surface and across the first aperture, a second conductive strip being formed on the second surface and across the second aperture;
- at least one post projecting from the first interior surface of the housing towards a second interior surface of the housing, the first interior surface facing the second interior surface;
- and
- a thermo electric cooler disposed on the housing, the thermo electric cooler configured to one of cool and heat at least a portion of the housing.

A method, comprising:
- sensing a condition associated with a cavity filter, the cavity filter including a housing defining a cavity, the housing including a bottom, at least one side wall and a cover, the bottom including a base having a first surface and an opposite second surface, the first surface being plated in a first conductive material, at least a portion of the first surface being an interior surface of the housing, the bottom including first and second apertures, a first conductive strip being formed on the second surface and across the first aperture, a second conductive strip being formed on the second surface and across the second aperture;
- obtaining, by a processor, a control parameter value based on the sensed condition;
- and
- controlling a thermo electric cooler disposed on the cavity filter based on the obtained control parameter value.
1 more element
A method, comprising:
- changing a temperature of a material forming at least a portion of a cavity filter to control at least one dimension of the cavity filter;
- wherein the cavity filter includes a housing defining a cavity, the housing including a bottom, at least one side wall and a cover, the bottom including a base having a first surface and an opposite second surface, the first surface being plated in a first conductive material, at least a portion of the first surface being an interior surface of the housing, the bottom including first and second apertures, a first conductive strip being formed on the second surface and across the first aperture, a second conductive strip being formed on the second surface and across the second aperture.
