Abstract
n [36] in differential configuration as the shared
antenna interface that merges a commutation-based linear-
periodically time-varying (LPTV) nonmagnetic circulator with
a downconverting mixer, directly providing BB signals at
its output. Each circ.-RX requires two sets of eight-phase
nonoverlapping clocks with 90
◦ phase shift to drive the
switches on either side of the N-path filter. The N-path filter
employs eight paths to decrease the TX-ANT loss, increase
the ANT-RX BB recombination g ain, and
