Abstract
This invention provides a phase detector with more than two detector units on a printed circuit layer. A detector set includes a pair of detector units or one detector unit, and a detector row includes a plurality of detector sets in one line. The phase detector includes a plurality of detector rows and each row has a detector set in one period, wherein all detector units are interleaved to have the same interval between any two adjacent detector units, which is defined as a pitch and the pitch is equal to one period dividing the detector pair number, which is the half sum of the number of one detector set for all rows.
