ABSTRACT:
A direct current (DC) isolated phase inverter and a ring hybrid coupler including the DC isolated phase inverter is provided. The ring hybrid coupler including the DC isolated phase inverter comprising: a first, second, third and fourth transmission line arm; a first port connected to the first arm, second port connected to the second arm, third port connected to the third arm and fourth port connected to the fourth arm; and a DC phase inverter inserted within one of the first, second, third and fourth arms, wherein the DC phase inverter comprises: a transmission line comprising a plurality of signal and ground traces, wherein the plurality of signal and ground traces are interchanged; and a plurality of capacitors disposed in series with the ground traces, wherein the plurality of capacitors isolate the DC phase inverter from a device connected to the transmission line.
