Packaged 7 mW, 1.2 GHz dynamic 60/61 GaAs prescaler

Abstract

A 7 mW, 400 MHz–1.2 GHz GaAs low-power dual-modulus prescaler has been designed and processed, using the DCFL approach and aligned technology. Dynamic logic allows significant power reduction and minimum component count. Phase noise measurements and frequency behaviour in a silicon PLL are comparable with common frequency synthesis systems.
