Methods for detecting phase and power difference by using a mixer configured with two symmetrically connected unit mixers with delay lines are proposed. The mixer having two detection curves achieves highly accurate phase detection for all phases, compared with a conventional mixer that has the stationary points 0 and π. The accuracy is demonstrated with a… CONTINUE READING
