General Notes:
1. Merrimac Phase Comparators provide two output
signals each of which is proportional to the phase
relation of the two inputs.
2. One output is proportional to the sine of the relative
phase angle between the RF and LO inputs while the
other output represents the cosine of the relative
phase angle between the inputs. Using the sine and
cosine outputs together resolves the inherent
π−period
ambiguity across four quadrants for both
outputs.
3. The phase comparator is an integrated assembly
consisting of a power divider, two balanced mixers
and a 90° quadrature hybrid. Two diplexers attenuate
the second harmonic (2 f
o
) at the outputs.
4. Custom designs are available that provide higher
precision and better accuracy. Inquiries concerning
your special applications are welcomed.
