Abstract
In this paper, we present a CPW-based 77 GHz 3-stage power amplifier MMIC for automotive radar systems. The power amplifier MMIC has been realized using a 130 nm <TEX>$In_{0.88}$</TEX>GaP/<TEX>$In_{0.4}$</TEX>AlAs/<TEX>$In_{0.4}$</TEX>GaAs metamorphic high-electron mobility transistors(mHEMTs) technology and an output stage with a cascode configuration. This produced a good output power and gain performance at 77 GHz. The fabricated power amplifier MMIC exhibited a small-signal gain of 18 dB, an output power of 17 dBm and 9 % power added efficiency(PAE) at 77 GHz with a total gate width of 800 <TEX>${\mu}m$</TEX> in the output stage. These performances could be useful to low-cost and small-sized components for 77 GHz automotive radar systems.
