Abstract
This paper describes the high performance design a power amplifier for Radio over Fiber (RoF) Technology at 2.4 GHz using Agilents HBFP-0450 transistor. Based on wireless network RoF technology has been proposed as a promising cost effective solution to meet ever increasing user bandwidth and wireless demands. In this network, a central station (CS) is connected to numerous functionally simple Radio Access Point (RAP) via an optical fiber. The only components required at the passive RAP are Electro Absorption Modulator (EAM) and antenna where EAM is used as a remote transceiver. There are practical limitations on the power that can produce by the passive RAP which can affect the dynamic range. In order to improve the dynamic range of passive pico cell RAP power amplifier is placed at the front end of RAP for the downlink transmission which operate in active mode. The central station (CS) is connected to numerous functionally simple RAP via an optical fiber in the RoF network. The design is based on the conjugate matching method which able to achieve the maximum gain. The performance of the design simulation done using Agilent Advanced Design System (ADS) software . The design has shown an acceptable behavior with gain of 13.172 dB. At the 1-dB compression point the output power is approximately 16.108 dB and the Power Added Efficiency (PAE) is 24.915 %.
