Abstract: A satellite includes a satellite housing, a temperature sensitive component carried by the satellite housing, and a thermal radiator carried by the satellite housing.

In the decoupled state, the temperature sensitive component and the thermal radiator are thermally decoupled.

Abstract: A multi-tile configured, two-dimensional phased array antenna architecture is configured of an gridwork of sub-array `tiles`, each of which contains a mechanically integrated and RF-integrated antenna elements and RF interface components therefor. Each tile is formed of a multilayer printed wiring board and supports a sub-array of antenna elements and their associated RF circuits, so that the tile itself is effectively an operative phased-array antenna. The gridwork supports the sub-array tiles in sealed engagement with the framework, whereby associated RF networks components at rear sides of the tiles are protected against the free space environment to which the antenna elements on front faces of the tiles are exposed. Each RF interface network contains signal processing circuitry for controlling the operation of a respective one or a set of the antenna elements on the front side of the tile.
