VCO Source Programs Arbitrary Waveforms

摘要

Frequency agility is a key requirement for a variety of military systems, including electronic warfare (EW), electronic countermeasures (ECM), secure communications, and electronic intelligence platforms. For these systems, conflicting requirements in technical performance, power management, packaging, and environmental surviv-ability often give rise to interesting and innovative designs. The engineers at Narda Microwave-East resolved these conflicts with the model 10512 signal source, currently available for applications to 3 GHz. It employs a unique mix of custom and standard components, novel printed-circuit-board fabrication techniques, and digital implementation of traditionally analog functions to produce a DSP-based, programmable arbitrary FM signal source with dual highly linearized voltage-controlled oscillators (VCOs).
