Design a High-Gain Wideband Two-Stage Cascode Low Noise Amplifier with Chebeyshiv Filter matching Technique

Abstract

This Paper presents the design of 1.6GHz-10.6GHz ulta-wide band (UWB) low noise amplifier (LNA) using pHEMT GaAs Process. The matching network uses lossy matching made up of lumped element. Under the software Agilent’s Advanced Design System (ADS) environment, the simulation results show a high gain ( ), fine flatness (<1dB), good noise characteristics (NF<2dB), and fine input/output return loss ( ) in the frequency range of the design.
