摘要/Abstract

摘要： With rapid development communication system, high signal to noise ratio (SNR) system is required. In high frequency bandwidth, high loss, low Q inductors and high noise figure is a significant challenge with on-chip monolithic microwave integrated circuits (MMICs). To overcome this problem, high Q, low loss transmission line characteristics was analyzed. Compared with the same inductor value of the lumped component and the transmission line, it has a higher Q value and lower loss performance in high frequency, and a 2-stage common-source low noise amplifier (LNA) was presented, which employs source inductor feedback technology and high Q low loss transmission line matching network technique with over 17.6 dB small signal gain and 1.1 dB noise figure in 15 GHz–18 GHz. The LNA was fabricated by WIN semiconductors company 0.15 μm gallium arsenide (GaAs) P high electron mobility transistor (P-HEMT) process. The total current is 15 mA, while the DC power consumption is only 45 mW.
