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.
Claims19
A phase detector, comprising:
- a plurality of detector rows arranged row-by-row, wherein each detector row includes a plurality of detector sets arranged in one line, and at least one detector set is arranged in one period for one row, and each detector set includes a pair of detector units or one detector unit, and all detector units regardless of the same or different rows are interleaved to have an equal interval between any two adjacent detector units, and the interval is defined as a pitch, which is equal to the length of one period dividing the unit number, which is the sum of the number of the detector units in one period for all rows.
A phase detector, comprising:
- a plurality of first detector units arranged in a first row;
- a plurality of second detector units interleaved with the plurality of first detector units in the first row;
- a plurality of third detector units arranged in a second row;
- and
- a plurality of fourth detector unit interleaved with the plurality of third detect units in the second row, wherein the first row and the second row are parallel with each other, wherein a distance between any two neighbor detector units from the plurality of first, second, third, and fourth detector units is the same.
