ABSTRACT:
A microwave device includes a circuit board having a microstrip layer, a ground plane, and a dielectric layer therebetween. The circuit board has a shield receiving slot for longitudinally receiving the end of a shield conductor of a coaxial cable. The coaxial cable also has an inner conductor having an end that extends longitudinally outwardly from the end of the shield conductor. The microstrip layer has an inner conductor contact adjacent the shield receiving slot that connects to the end of the inner conductor. The device may include a conductive layer in the shield receiving slot to connect to the ground plane. The shield receiving slot may have a T shape and extend through the circuit board. The device may include a mounting fixture connecting an end of the shield conductor to the circuit board.
