S-to-X Band 360-Degree RF Phase Detector IC Consisting of Symmetrical Mixers and Tunable Low-Pass Filters

This paper demonstrates that a 360° radio-frequency phase detector consisting of a combination of symmetrical mixers and 45° phase shifters with tunable devices can achieve a low phase-detection error over a wide frequency range. It is shown that the phase detection error does not depend on the volt...
