S. Lucyszyn et Id. Robertson, ANALOG REFLECTION TOPOLOGY BUILDING-BLOCKS FOR ADAPTIVE MICROWAVE SIGNAL-PROCESSING APPLICATIONS, IEEE transactions on microwave theory and techniques, 43(3), 1995, pp. 601-611
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.
