Abstract
This paper presents the design and performance of a single-ended and a balanced MMIC frequency doublers from 38 to 76 GHz, realized in CPW technology using 0.15-μm PM-HEMTs on GaAs. These circuits have demonstrated an output power of nearly 10 dBm for a 16-dBm 38-GHz input signal. Their compact size and good power performance makes them attractive candidates for application in FMCW collision-avoidance radar systems, eliminating the need for W-band amplifier stages. A table-based large-signal HEMT model has been used successfully for the design of both circuits, resulting in very good agreement between predicted and measured power performance.
