Abstract
In order to meet the demand for mass production of 77 GHz automotive radar systems, a low cost and high performance 38/77 GHz 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 76.5 GHz. Also, highly reliable RF operation of a bare MMIC chip is obtained with less than 0.7 dB reduction in output power during 10[superscript 6] hr at V[subscript d]=4 V and T[subscript a]=25[degrees]C in air.
