<p>Two transmit/receive (T/R) channels are implemented in a single T/R module providing combined functions, control and power conditioning while utilizing a single multicavity, multilayer substrate comprised of high temperature cofired ceramic (HTCC) layers. The ceramic layers have outer surfaces for providing three dimensional routing of both shielded RF and DC power and logic control signals. Monolithic microwave integrated circuits, attached to DC power and logic control signals, are located in multilevel cavities formed in the substrate and bonded directly to a heat sink plate, secured to the bottom of the substrate. DC power conditioning is provided by a capacitive bank supplying supplementary power to the module during peak power operation. The T/R module is one module of an array of like T/R modules coupled to an active aperture of a radar system.</p> |
