Patent ID: 7109922

Claim:
A transceiver for a millimeter wave signal, comprising: a printed circuit board (PCB), comprising PCB microstrip lines and PCB waveguide apertures; one or more transmitter modules mounted on the PCB, each transmitter module comprising: a single transmit microstrip-waveguide transition adapted to convey millimeter waves and coupled to one of the PCB waveguide apertures so as to form a transmit waveguide-waveguide transition; a transmit microstrip-microstrip transition coupled to one of the PCB microstrip lines so as to form a PCB-transmitter module microstrip-microstrip transition; and transmit active components coupled to receive a first reference frequency from the PCB-transmitter module microstrip-microstrip transition, to generate the millimeter wave signal therefrom, and to transmit the millimeter wave signal via the transmit waveguide-waveguide transition; and one or more receiver modules mounted on the PCB, each receiver module comprising: a single receive microstrip-waveguide transition adapted to convey millimeter waves and coupled to one of the PCB waveguide apertures so as to form a receive waveguide-waveguide transition; a receive microstrip-microstrip transition coupled to one of the PCB microstrip lines so as to form a PCB-receiver module microstrip-microstrip transition; an output port; and receive active components coupled to receive a second reference frequency from the PCB-receiver module microstrip-microstrip transition, to receive the millimeter wave signal from the waveguide-waveguide transition, to generate a down-converted signal in response to the second reference frequency and the millimeter wave signal, and to transfer the down-converted signal via the output port.
