This paper presents design of Low Noise Amplifier (LNA) which operates at 1.6 GHz for Global Positioning System (GPS) application on IHP SiGe BiCMOS 0.25 node. LNA performance is optimized for the power constraint of 2 mW. Simultaneous noise and power match is achieved. The cascode topology with resonating load is used to maximize gain at 1.6 GHz. LNA achieves gain of 14.8 dB and noise figure of 0.96 dB. The LNA exhibits IIP3 of -15.3 dBm for 2-tone test frequencies of 1.6 GHz and 1.62 GHz. The 1 dB compression point of LNA is -20.6 dBm at 1.6 GHz. Cadence tool is used for design and optimization of LNA.
