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.
