DetectorsSource: Skyworks Solutions, Inc.
Skyworks Solutions' family of sampling phase detectors utilize automated chip on board manufacturing technology to provide a small footprint surface mount device with excellent microwave performance. Sampling phase detectors are used to phase lock a microwave VCO to a stable reference source at a sub-multiple frequency. The sampling phase detector consists of a step recovery diode, pair of coupling capacitors and a Schottky diode based microwave mixer. This phase detector family uses a selected step recovery diode chip whose carrier lifetime and transition time are appropriate for use in applications allowing reference frequencies below 50 MHz and microwave VCO frequencies as high as 22 GHz. The SPD1101-111, SPD1102-111 and SPD1103-111 utilize low, medium and high barrier Schottky diodes capable of efficient high frequency mixer performance and may be selected according to the available power generated by the microwave VCO.
Skyworks directional detectors incorporate innovative directional technology along with our advanced Schottky diode technology to produce a wide bandwidth, wide power range detector circuit with excellent directivity and low insertion loss that is easily temperature compensated with a single differential amplifier. This product is well-suited for use in radio infrastructure transmitter automatic level control systems, power amplifier monitors, and many other applications.
