  • Patent number: 7257381
    Abstract: A self-tuned millimeter wave transceiver module includes a microwave monolithic integrated circuit (MMIC) having at least one amplifier. A controller is operatively connected to the MMIC for sensing amplifier operating conditions and tuning the at least one amplifier to an optimum operating condition. The controller includes a surface mounted microcontroller chip operatively connected to the MMIC.
    Type: Grant

  • Patent number: 7005740
    Abstract: A thick film millimeter wave transceiver module includes a base plate and a multi-layer substrate board having a plurality of layers of low temperature transfer tape received on the base plate. The different layers can vary. They can include a DC signals layer having signal tracks in connection; a ground layer having ground connections; a device layer having capacitors and resistors embedded therein; and a top layer having cut-outs for receiving MMIC chips therein. A solder preform layer is located between the device layer and the top layer for securing any MMIC chips. A channelization plate is received over the multi-layer substrate board and a channel is formed to receive MMIC chips and provide isolation between transmit and receive signals.

  • Patent number: 6873044
    Abstract: A microwave monolithic integrated circuit (MMIC) package includes a MMIC and a base plate that is matched as to its coefficient of thermal expansion (CTE) with the MMIC. A solder preform is contained on the base plate. The MMIC is mounted on the solder preform. A chip cover covers the MMIC and are configured with respective portions that engage each other such that any pads on the MMIC are exposed for wire and ribbon bonding. The base plate and MMIC are secured together by a solder flow process from the solder preform.
