Digital dynamic frequency dividers for broadband application up to 60 GHz

Abstract

A broad band dynamic frequency divider based on pseudomorphic Alo.2Gao.sAs/ Ino.2sGao.7sAs MODFETs and passive loads will be presented. Stable operation from 28 GHz up to 51 GHz with a power consumption of 440 m W could be shown. SPICE network simulation predicts operation in the 35 GHz-60 GHz range for a divider circuit using an advanced E/D AlGaAs/ lnGaAs MODFET process.
