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 onto a circuit formed on a base substrate and having large passive elements. Push-pull amplifiers are presented as examples in which the multiple function operation is the combining of amplifiers whose active devices are on a single chip. Electromagnetic coupling, impedance matching and signal transmission are variously provided by the use of strip lines, slotlines, coplanar waveguides, and a slotline converted into a coplanar waveguide.
