Abstract

This paper presents 5-6 GHz front end Low Noise Amplifier application for IEEE standard 8021.1 g system for WLAN application. This amplifier uses FHX76LP Low noise SuperHEMT device designed for DBS application from Eudyna Device USA Inc. The paper present circuit design, simulation and measurement, including circuit analysis and verification of a Low Noise Amplifier (LNA) system at 5.75 - 5.85 GHz with the input/output return loss less than 10 dB. The gain of this Low Noise Amplifier (LNA) system is 57 dB and Noise Figure of 1.16 dB. The Low Noise Amplifier (LNA) system requires circuit analysis and verification in terms of circuit characteristic and performance. This project uses Ansoft Designer Software which available in the faculty. With this development, the amplifier can be used as part of front end receiver for future Wireless Local Area Network (WLAN) at 5.8 GHz.
