Abstract

This report is investigated the analysis, design and implementation of high linearity power amplifiers for WCDMA application. The basic study background about high linearity power amplifier and specification of WCDMA application have been analyze before the design process start. The basic procedure in designing high linearity power amplifier require DC biasing, stability checking, input and output matching and maximum output power consumption. In high linearity power amplifier design, maximize the linearity and also the efficiency is one of the challenging task. In order to solve that, topology of power amplifier has been made to compare the result of the power amplifier. The design topology are Single Stage Amplifier, Balanced Amplifier and Feedback Amplifier. The best performanced from this three design is from Balanced Amplifier which gives higher return loss and output power which are -20.236 dB and 24.571 dB. Meanwhile the Feedback Amplifier gives higher gain which is 27.452 dBm. The simulation work is done by using Advanced Digital Software (ADS) and will be compared with the actual circuit. The optimization function of the software can help in getting accurate result.
