Abstract

This paper discusses the design, fabrication, and testing of a three-stage microstrip pHEMT low noise amplifier (LNA) for automotive radar applications. The LNA goals were 4.5 dB noise figure and greater than 12 dB of gain at 76-77 GHz. The LNA as fabricated provides 10 dB of gain over the 70-78 GHz frequency range, with 4 dB noise figure at 77 GHz and better than 5 dB noise figure over the 75-79 GHz band. Based on a review of comparable work to date, the noise figure demonstrated at 77 GHz with this LNA surpasses that achievable with other low noise amplifiers.
