In order to meet the demand for mass production of 77GHz automotive radar systems, a low cost and high performance 38/77GHz AlGaAs/InGaAs PHEMT MMIC transmit amplifier with a multiplier has been realized. The chip is packaged in an inexpensive conventional non-hermetic package. Excellent power performance is demonstrated with a 15dBm output power and 7dB maximum conversion gain from 38 to 76.5GHz. Also, highly reliable RF operation of a bare MMIC chip is obtained with less than 0.7dB reduction in output power during 106 hr at Vd=4V and Ta=25°C in air.
