Abstract :
A broadband dynamic frequency divider based on pseudomorphic Al/sub 0.2/Ga/sub 0.8/As/In/sub 0.25/Ga/sub 0.75/As MODFETs and passive loads is presented. Stable operation from 28 GHz up to 51 GHz with a power consumption of 440 mW 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/InGaAs MODFET process.<>
