This letter presents the simulation and measurement results for a miniaturized rat‐race hybrid using six lumped‐element components. The hybrid was implemented on an FR4 substrate using chip inductors and chip capacitors. For the 530‐ to 620 ‐ MHz frequency range, the rat‐race hybrid exhibited power splits of −3.4 ± 0.7 dB, return losses of >18 dB, an isolation between output ports of >24 dB, and errors in the desired relative phase difference between output ports of <5°. © 2016 Wiley Periodicals, Inc.
