ANALOG REFLECTION TOPOLOGY BUILDING-BLOCKS FOR ADAPTIVE MICROWAVE SIGNAL-PROCESSING APPLICATIONS

The synthesis and realization of an analog-phase shifter, delay line, attenuator,and group delay synthesizer-are presented, These variable c ontrol devices are ad implemented using the same generic single stage reflection topology, The optimum conditions of operation have been det ermined and the corresponding group delay behaviors have been investig ated to produce simple design equations, As proof-of-concepts, monolit hic technology has been used to realize an X-band, phase shifter, dela y line, and attenuator, Hybrid technology has been used to realize an L-band, group-delay synthesizer, Because of the high levels of perform ance measured, these control devices are ideally suited for use as gen eral building blocks in adaptive signal processing applications, inclu ding large phased array applications.
