摘要： A transceiver apparatus comprising a software-definable-radio-transceiver architecture. The transceiver apparatus comprises at least one up-conversion path including at least one configurable micro-electro-mechanical-system (MEMS) transmit filter communicatively coupled to transmit output from a digital-to-analog converter to an antenna, and at least one down-conversion path including at least one configurable-MEMS-receive filter communicatively coupled to transmit signals received from the antenna to an analog-to-digital converter. The at least one configurable-MEMS-transmit filter prevents interference on the up-conversion path from signals transmitted from the antenna. The at least one configurable-MEMS-receive filter prevents interference on the down-conversion path from signals transmitted to the antenna. A plurality of upconversion and downconversion paths can operate simultaneously and on different channel frequencies.

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.
