High Speed Synthesizers for Satellite Application
Abstract
High-speed wide-band microwave synthesizers are required for many frequency-hopped satellite communication systems. These synthesizers must be of high-reliability design, of compact size, and light weight, in addition to having low DC power requirements. This paper describes a space-flight qualified synthesizer system which meets these requirements and provides operational redundancy. The circuit technology utilized to implement an indirect synthesis techniques using a VCO and phase-locked loop is described, together with circuitry for fast frequency switching, fine frequency tuning and control. The performance of major components is discussed in addition to overall synthesizer system performance.
