Cost-Effective VCOs Replace Power-Hungry YIGs
Phase noise is the curse of many a communications system, and one of the key performance parameters that most oscillators strive to minimize. System designers have long recognized the yttrium-iron-garnet (YIG) oscillator for its broadband, low-noise, high-frequency capabilities. But YIG sources are also power hungry and physically large. The mechanical design, with a YIG sphere mounted in the air gap of an electromagnet, is not conducive to integrated-circuit (IC)...

Low-Noise VCOs Conquer Wide Bands
Bandwidth and phase noise are two of the leading requirements for signal-generating components in modern communications equipment. Voltage-controlled oscillators (VCOs) have been the frequency source of choice for many wired-, wireless-, and...
