Low Noise and high linearity Wide-band Low Noise Amplifier for 5G Receiver Front End System

Abstract

This work Demonstrates a wideband LNA for 5G\nreceiver front end modules with high linearity, Low noise reused\ntopology has an inter stage wideband inductor based two\ncommon source cascade stages. The configuration provides the\nbias current; better Noise figure increases the forward gain. By\nproviding RC Series network at gate terminal of second stage the\nreturn losses are reduced and stability will be increased. After\npre and post simulation all parameters are better than the\nexisting LNAS. After post simulation results, the Noise figure is\nachieved less than 1dB and forward gain as flat 16dB for wide\nband width of 1.5 – 5.5 GHz. At the 1dB compression point the\noutput is 20dbm achieved and OIP3 IS +40dbm is achieved. The\nchip size of an LNA along with pad is 0.64mm2. The design is\nGaAsp HEMT process at 50nm technology.
