Abstract: A surface-mountable packageless hybrid comprising a ceramic substrate with circuit elements attached to a top surface of the substrate is soldered to a ground pad on a printed circuit board. A high performance transition for microwave frequency signals between the circuit board and the substrate is provided by RF connections comprising three gull wing shaped leads connecting three solder pads on the printed circuit board to three solder pads on the substrate, the solder pads having capacitive matching sections to compensate for lead inductance. The center lead conducts the microwave frequency signal while the outer leads are grounded.
