Abstract
A means of connecting a plurality of essentially identical active devices is presented for the purpose of multifunction and multiple function operation. These devices, mounted on a chip, are flip-mounted to a circuit motherboard having large passive elements. A push-pull amplifier is presented as an example in which the multiple function operation is the combining of amplifiers whose active devices are on a single chip. The electromagnetic coupling, impedance matching and signal transmission are variously provided by the use of striplines, slotlines, coplanar waveguides, and a slotline converted into a coplanar waveguide. In particular, a conversion of a split coplanar slotline to dual coplanar waveguides provides signal transmission to a pair of transistors flip-mounted onto the coplanar waveguides.
