I For Phase Locked VCOs to 22 GHz I Reference Frequencies Below 50 MHz I New Surface Mount Package Design I Small Footprint (90 x 110 Mils) I Automated Chip on Board Construction
Description
Alpha has redesigned its product line of sampling phase detectors using automated chip on board manufacturing technology to provide a more uniform, surface mountable, small footprint device without sacrificing the microwave performance of the original design. Sampling phase detectors are used to phase lock a microwave VCO to a stable reference source at a submultiple frequency. The sampling phase detector consists of a step recovery diode, capacitors and a microwave mixer consisting of series pair Schottky diodes.
