    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: 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: An electrical phase shifting circuit element of the reflection type including a quadrature coupler branch network, a matched pair of selectively coupled transmission lines and an electrical switching element corresponding to each pair of transmission lines, all being separated distributively from each other and a ground plane by a dielectric material, is disclosed. One end of one transmission line of each pair is connected to a corresponding phase splitting port of the quadrature coupler and another end of the other transmission line of each pair is coupled to the switching element which is preferably a pin diode. The pin diodes may be governed by a common switching signal to electrically connect and disconnect the another ends of the other transmission lines to the ground plane. The transfer between the connecting and disconnecting states renders a phase shift to the RF signal at the output port of the quadrature coupler, the magnitude and direction of the rendered phase shift being a function of the selected coupling of the transmission line pairs. More specifically, one transmission line of each pair may have a preset length of approximately one-quarter wavelength of the desired frequency of the input RF signal and the length of the other line in each pair may be selected in the range of 0 to the one-quarter wavelength dimension. The magnitude and direction of the phase shift in the output RF signal caused by the transfer of states of the electrical switching element is based on the selected length of the other transmission line in each pair.

    摘要: A ridge waveguide filter which is formed of metallized blind vias in a plurality of contiguous layers of a dielectric medium including low temperature cofired ceramic (LTCC), high temperature cofired ceramic (HTCC) or organic printed wiring boards (PWB) in the fabrication of the waveguide sidewalls and solid ground planes to provide top and bottom walls as well as in the formation of a plurality of ridge waveguide sections in an embedded ridge waveguide structure. Patterns of conductive metal are selectively printed on the outer surface of certain dielectric layers to electrically short all the vias in the ridge waveguide sections and the adjacent wall vias so that the elements behave as though they comprise a solid metal structure.
