Abstract: An apparatus includes a laminate and a lid. The laminate generally includes a dielectric layer between a first conductive layer and a second conductive layer. The first conductive layer may include a probe configured to transfer a radio-frequency signal in a millimeter-wave band. The second conductive layer may be configured to provide a continuous ground plane parallel to the probe and separated from the probe by the dielectric layer. A plurality of channels may be (a) formed into a side of the second conductive layer opposite the dielectric layer, (b) formed to a depth less than a thickness of the second conductive layer, and (c) sized to permit gasses formed while securing the laminate to a substrate to escape from between the laminate and the substrate. The lid may be in contact with the first conductive layer.

The first circuit may have a first diode and a second diode connected as anti-parallel diodes and physically adjacent to each other in a substrate. The second circuit may have a third diode and a fourth diode connected as anti-parallel diodes and physically adjacent to each other in the substrate. The first circuit and the second circuit may be configured to mix two input signals to generate an output signal. A polarity of every other physically neighboring diode may be reversed.

Abstract: An apparatus includes a package, a wall and a lid. The package may be configured to mount two chips configured to generate one or more signals in a millimeter-wave frequency range. The wall may be formed between the two chips. The wall generally has a plurality of conductive arches that attenuate an electromagnetic coupling between the two chips in the millimeter-wave frequency range. The lid may be configured to enclose the chips to form a cavity.
