Patent ID: 7005740

Claim:
A thick film millimeter wave transceiver module comprising: a base plate; a multi-layer, thick film substrate board formed from a plurality of planar sheets of low temperature, co-fired ceramic material stacked and bonded together without intermediate conductive sheet layers so as to constitute a single, planar substrate board having one planar bottom surface and one planar top surface, said substrate board comprising: a DC signals layer formed from a separate sheet and having embedded DC signal tracks and connections, a ground layer formed from a separate sheet and having ground connections, a device layer positioned over said ground layer and formed from a separate sheet and having capacitors and resistors embedded therein, a plurality of MMIC chips mounted on the top surface and operable to transmit and receive millimeter wavelength signals and connected to capacitors and resistors in the device layer; and a channelization plate received over the top surface of the substrate board and having channels formed to receive the MMIC chips and provide air isolation between any transmit and receive signals.
