A 13GHz GaAs dynamic frequency divider and prescaler IC

Abstract

GaAs ICs HAVE a great potential, particularly in satellite and microwave communication systems due to their ultrahigh speed, low power consumption and radiation hardness. In a local oscillator circuit, a prescaler operating at a higher frequency with a lower power is required to simplify the phase lock loop and to improve phase and frequency stability. This paper will describe a 13.2GHz GaAo binary dynamic divider with 115mW power dissipation and an 8.5GHz GaAs 1/32 prescaler IC with 540mW power dissipation.
