摘要： Two discrete transmit/receive (T/R) channels are implemented in a single common T/R module package having the capability of providing combined functions, control and power conditioning while utilizing a single multi-cavity, multi-layer substrate comprised of high temperature cofired ceramic (HTCC) layers. The ceramic layers have outer surfaces including respective metallization patterns of ground planes and stripline conductors as well as feedthroughs or vertical vias formed therein for providing three dimensional routing of both shielded RF and DC power and logic control signals so as to configure, among other things, a pair of RF manifold signal couplers which are embedded in the substrate and which transition to a multi-pin blind mate press-on RF connector assembly at the front end of the package. DC and logic input/output control signals are connected to a plurality of active circuit components including application specific integrated circuits (ASICs) and monolithic microwave integrated circuit chips (MMICs) via spring contact pads at the rear of the package. The MMICs which generate substantially all of the heat are located in multi-level cavities formed in the substrate and are bonded directly to a generally flat a heat sink plate which is secured to the bottom of the substrate and acts as a thermal interface to an external heat exchanger such as a cold plate. DC power conditioning is also provided by a capacitive bank type of energy storage subassembly externally attached to the rear of the module package for 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.

摘要： A radio frequency semiconductor switching device (S) is formed on an MMIC structure (C) including a switching circuit element (12) having four semiconductor switching units (68, 70) with each adapted for receiving a gate control signal. A level shift circuit (10) generates a biasing voltage signal communicated of the switching units (68, 70) for biasing the switching units (68), and provides an output that swings between approximately one diode drop above ground and a negative voltage to bias the switching circuit elements (68 and 70) for reduced loss. The level shift circuit (10) is responsive to an externally provided control signal (58). The switching units (68, 70) are formed into a grouping of at least, a first and a second set (76, 78) of interconnected semiconductor switching units (68, 70) with each set (76, 78) having gates of at least two of the interconnected switching units (68, 70) connected with the level shift circuit output (60, 62). Both the switching units (68, 70) and the level shift circuit (10) are formed on the MMIC structure (C).

摘要： A transmit/receive (T/R) module adapted for use in a radar system. The module has a unified structure including a layered substrate on and in which two T/R channel circuits are integrated. The channel circuits make use of power distribution, channel controller, and RF signal routing circuitry, partly on a channel shared basis. In the RF routing circuitry, respective coupler elements are employed to combine RF receive signals for output to an RF receive manifold and to split an RF transmit signal from a transmit manifold into separate RF transmit signals for input to the T/R channel circuits.
