A plurality of end caps engagable with a microwave cavity each have an underside configured differently to cause the microwave cavity to have different electrical responses depending on which end cap engages the microwave cavity. A microwave device includes a cylindrical cavity and an end cap movable within the cavity to change its axial position within the cavity thereby varying the volume and the electrical response of the cavity.

A modular payload structure providing standardized thermal, electrical and mechanical interfaces. The modular arrangement of the present invention has fixed radiator panels that have standard thermal and mechanical interfaces, allowing communication modules to 'plug in' directly to the payload structure. In the case of high thermo-energy dissipating modules, heat pipes on the modules connect to the thermal interfaces and move energy from the modules to the thermal interfaces of the radiator panel.
