This paper describes how a broadband, 1.5 V, 0.85 - 13.35 GHz low noise amplifier in 0.15 mm 85 GHz PHEMT -process is synthesized to simultaneously meet multiple design specifications such as bandwidth, noise f0 igure, power gain and power consumption. Power-constrained synthesis technique is used to design the broadband amplifier. The -simulated peak S21 is 19.8 dB, maximum noise Figure is 2.5 dB, 3-dB bandwidth is 12.5 GHz and power consumption is 73.5 mW. The calculated Figure of merit (FOM) is better than many reported broadband low noise amplifier (LNA).
