Abstract

See full text

Right angle transition to circuit. A system includes a conductive plate, coaxial transmission line, a circuit, parallel to the conductive plate, and a right angle transition from the coaxial transmission line to the circuit. The transmission line includes a center pin protruding through a hole in the plate, an outer conductor formed by a conductive surface of the hole, and air dielectric between. The circuit includes a top conducting layer (TCL), ground plane with cutout, and an insulating substrate between the TCL and ground plane that abuts the pin. The transition includes the pin, a conductive element connecting the center pin to the TCL, the outer conductor, the air dielectric, the abutment of the substrate against the pin, and the cutout. The abutment and cutout minimize manufacturing variations regarding distance between the pin and the ground plane. The transition tunes out inductance introduced by bonding the pin to the TCL.
