Abstract
A class of RF dispersive-delay structures (DDSs) with input-quasi-reflectionless behavior is reported. It is based on the exploitation of complementary-diplexer circuit networks, in which the out-of-band RF-input-power echoes reflected by the main bandpass-filter-(BPF)-type channel are dissipated by the resistively-terminated auxiliary bandstop-filter-(BSF)-type channel. Specifically, it is shown that the influence of the absorptive auxiliary channel over the in-band transmission-phase response of the main channel can be compensated to obtain the desired transmission-phase profile in the overall RF device. Thus, a multi-functional RF component with co-integrated DDS, BPF, and low-RF-input-reflection capabilities can be designed. Optimization-based synthesis examples at the coupling-routing-diagram level of third-and fifth-order input-quasi-reflectionless BPF-based DDSs, for which the in-band group-delay pattern increases linearly with frequency, are presented. Moreover, for practical-validation purposes, a 2-GHz microstrip prototype is built and measured.
