Stacked multistage lumped element circulator

A. Schuchinsky

Research output: Contribution to conferencePaperpeer-review


The novel concept and architecture of the vertically stacked multistage circulator with a single source of dc magnetic bias has been proposed. The distinctive features of the new arrangement are discussed and the main aspects of the circulator design, including the dc magnetic bias and concurrent thermal stabilization of multiple junctions, are presented. The experimental prototype of the VHF stacked double isolator exhibits low loss, high isolation, excellent thermal stability and the high power handling capability. The proposed class of multistage circulators can significantly increase dynamic range of the transceivers for the RF front-end of the emerging white space UHF/VHF applications.
