General Notes:
1. Merrimac Phase parators 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 parator is an integrated assembly consisting of a power divider, two balanced mixers and a 90° quadrature hybrid. Two diplexers attenuate the second harmonic (2 fo) at the outputs. 4. Custom designs are available that provide higher precision and better accuracy. Inquiries concerning your special applications are weled.
