Abstract

A coplanar regenerative frequency divider MMIC based on 0.15 /spl mu/m pHEMTs on GaAs for 94/47 GHz frequency conversion has been developed, achieving a bandwidth of 2-3 percent for stable division. A very low conversion loss of 2.5 dB was obtained with an input level of -2 dBm and a DC power consumption of 8 mW, without using additional buffer amplifiers. The frequency of operation can be tuned by a varactor diode in the feedback network.
