ABSTRACT:
ABSTRACTA transceiver (20) for a millimeter wave signal, consisting of a PCB (140) having PCB microstrip lines (141) and PCB waveguide apertures (159), and one or more transmitter modules (22) and one or more receiver modules (24, 26, 28) mounted on the PCB. Each module has a single microstrip-waveguide transition (34, 48) and a microstrip-microstrip transition (47, 49). The microstrip-waveguide transition of each module couples to one of the PCB waveguide apertures via a PCB-module waveguide-waveguide transition (167). The microstrip-microstrip transition of each module couples to one of the PCB microstrip lines via a PCB-module microstrip-microstrip transition (165). The PCB-module transitions are low tolerance, facilitating implementation of the transceiver.
