    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 or low temperature cofired ceramic 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. An RF connector assembly for coupling transmit and receive signals to and from the module is located at the front of the package. The RF transmit power amplifiers which generate most of the heat in the module package are located in a first pair of cavities formed in the substrate directly behind the RF connector assembly and are mounted directly on a pair of flat heat sink plates which are secured to the bottom of the substrate and acts as a thermal interface to an external heat exchanger such as a cold plate. A second pair of cavities in which are located the RF receive signal amplifiers and their respective receiver protector elements, is located beside the first pair of cavities directly behind the RF connector for reducing RF signal loss.

    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 planar dielectric substrate supports a stripline conductor therein. A conductive housing has one or more recesses for receiving a dielectric and a conductive cover is mountable over the dielectric in contact with the housing to enclose the dielectric and isolate the stripline from adjacent structures. The housing and cover have aligned slots disposed on opposite sides of the dielectric and transverse to the stripline for providing coupling of signals between the stripline and the slot. An aperture is formed in the housing in communication with the slot.Other embodiments of the invention include impedance matching means for either or both of the stripline and the aperture for optimizing the efficiency measured in terms of VSWR of the radiator.

    摘要： Loop radiating elements for microwave frequencies which result in balancedower division at the feed points and equi-phase currents in the radiating segments are in the form of an Alford loop design having a "kink" in the stripline path on the side of a printed circuit board opposite the cross-over to restore equal path lengths on both sides of a central feed terminal. Alternatively, the radiating segments of a loop may be in the form of end-loaded bent dipoles which are dual-fed on diametrically opposite points of the loop with equi-phase and amplitude signal. The result is loop radiating elements which have an axial null with a symmetrical doughnut radiating pattern.
