Design of a 2-Stage Broadband Low Noise Amplifier Based on the Agilent ADS

Abstract:

The noise coefficient and the power gain of a low noise amplifier affect the whole performance of the receiver. This paper presents the design and simulation of 2-stage low noise amplifier using the MGA633P8 and TQP3M9028’s S parameters to set S2P files. Not only analyze how to insert elements to match a broadband circuit, but also make some optimization by using the Agilent ADS in the case of small signal. Simulation results show that the proposed work implements a high performance of 2-stage low noise amplifier which works at 824 MHZ to 1980 MHZ, the gain is greater than 25 db, the noise coefficient is less than 0.6, input and output standing wave ratio (SWR) are both less than 1.3.
