ULTRA-WIDE BAND CIRCULATORS WITH SEQUENTIALLY-SWITCHED DELAY LINE (SSDL)

摘要

A passive circulator utilizing sequentially-switched delay lines (SSDL) in which delay line sections are sequentially turned on and off to achieve non-reciprocity to provide rejection/separations between different signals at the same/similar frequency, such as between a transmitted and received signal. The circulator is well-suited for on-chip integration and can be utilized across a wide frequency range. Various embodiments are described for separating signal waveforms.
