چکیده

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 15 dBm output power and 7 dB maximum conversion gain from 38 to 76.5GHz. Also, highly reliable RF operation of a bare MMIC chip is obtained with less than 0.7 dB reduction in output power during 106 hr at Vd = 4V and Ta = 25◦C in air.
