Abstract

The major goal of this project is to design and simulate a radio frequency (RF) front end of Radio Access Point (RAP) at 2.4 GI-lz for Radio over Fiber technology (RoF) using Advanced Design System (ADS) simulator. The focus of design is only for downlink transmission which consists of bandpass filter (BPF) and power amplifier. BPF is needed to remove out undesired frequency from nonlinear effect of fiber and pass through the signal at the operating frequency. In order to improve the dynamic range of passive picocell (RAP), the power amplifier is placed between the electro absorption modulator (EAM) and the antenna. Picocells use power lower than 30 dBm. The implementation of design is based on micro-strip technology and the analyses of scattering parameters are concerned in the simulation which presents the gain and return loss of the front end. At the end of design, the combination between parallel couple BPF and power amplifier is purposed as a RF front end of RAP for RoF technology.
