Abstract :
Shallow p+-regions in GaAs, formed by Cd ion implantation, have been used as the gate region for GaAs JFETs. 0.7 μm gate length JFETs demonstrated a transconductance of 165 mS/mm a saturation current of 130 mA/mm, an ft of 26 GHz, and an f max of 42 GHz. These frequency metrics are superior to previous Zn-gate JFETs of similar dimensions
