Abstract :
A novel technique utilizing harmonic modulation and positive feedback is proposed for microwave frequency division. A prototype divide-by-six prescaler is successfully designed and fabricated in an analog-digital GaAs MMIC. Remarkably low DC power operation (only 1.2 V/spl times/6 mA) is achieved at frequencies above 10 GHz. This could pave the way for dry-battery-driven user terminals in multimedia satellite communication systems.
