Oscillators, amplifiers, and frequency doublers at 38 and 77 GHz have been fabricated using direct ion-implanted GaAs MESFETs and CPW. The 38-GHz VCO delivers 12 d8m of power and the 77-GHz amplifier has 7.5 dB of gain. The various circuit results demonstrate that the direct ion-implanted GaAs MESFET process is a low-cost alternative to more expensive epitaxial device technologies for a wide variety of existing and emerging millimeter-wave circuit applications.
