Abstract

This paper presents a novel implementation of a wideband Low Noise Amplifier (LNA) for wireless communication, 4G Long Term Evolution (LTE) and wireless communication systems. Traditionally, CMOS based designs are fabricated for 4G applications. The proposed LNA design is based on a balanced configuration using ultra low noise Pseudo morphic High Electron Mobility Transistor (pHEMT) which has a fast switching response. The LNA exhibits a wideband frequency response from 1.9 to 2.4 GHz which makes it suitable for variety of wireless and mobile communication applications. The designed LNA has a NF of 0.588 dB with unconditional stability along with available gain of 12.850 dB. The LNA exhibits 20 dBm output power at 1dB gain compression and 28.5 dBm output at 3^rd order intercept.
