A package is provided for a pair of microwave semiconductor devices, such package comprising upper and lower mating covers, each one of such covers having bonded thereto a corresponding one of the pair of microwave semiconductor devices. With such arrangement, after the devices are bonded to the cover to form a component of the package, the effective impedance of the thus formed component is electrically characterized, or measured. Having characterized a large quantity of such components, the components are then sorted into bins with components having substantially matched characteristics being placed in a common one of the bins. Pairs of such components in a common bin are used as the upper and lower cover for the package. Thus, assembly time is significantly reduced since additional matching compensation techniques are not required.

A network having a plurality of network ports includes a plurality of substantially identical independent components, each one thereof having a plurality of ports, the degree of coupling among the ports of each component being characterized by a predetermined scattering coefficient matrix. A plurality of feed networks is included, each one having: a first port corresponding to one of the plurality of network ports; and, a plurality of second ports each one being coupled to a corresponding one of the plurality of ports of each one of the plurality of components, the degree of coupling among the first port and the plurality of second ports of each of the feed networks being characterized by a predetermined scattering coefficient matrix. The plurality of feed networks and the coupling thereof to the components characterize the network with a scattering coefficient matrix, relating the coupling among the network ports, different from the scattering coefficient matrix characterizing each one of the components. The plurality of feed networks and the coupling thereof to the components provide a pair of the network ports with a degree of coupling less than the degree of coupling between the pair of component ports coupled to said pair of network ports.

A digitally controlled reflective type phase shifter wherein radio frequency energy is fed to an input/output port of the phase shifter and then coupled from the phase shifter at the input/output port, the phase shifter providing one of a plurality of predetermined phase shifts between the fed energy and the coupled energy selectively in accordance with a control signal. The phase shifter includes: a coaxial transmission line with an inner conductor and an outer conductor, a first end of the inner conductor and a first end of the outer conductor providing the input/output port; a conductor connected to the second end of the outer conductor, such conductor being dielectrically spaced from a second end of the inner conductor; and, a plurality of switches, disposed between different portions of the second end of the inner conductor and the conductor and responsive to a control signal, for electrically connecting a selected one or ones of said different portions of the second end of the inner conductor to the conductor while unselected ones of the different portions of the second end of the inner conductor remain dielectrically spaced from the conductor.
