Abstract: Recently, Data communication using 2.45GHz ISM band for wireless networks such as Bluetooth, Wireless LAN, wireless video, audio has found widespread use for the last few years. The RF amplifiers & antenna are the critical components in the RF front end & are expected to provide a suitable output power at a very good gain with high efficiency and linearity. The amplifiers will be based on the components such as bipolar junction transistor, field effect transistor & RFIC amplifier to see their characteristics & performances like output power level, gain, linearity, efficiency, 1dB compression point & inter-modulation in 2.4~2.5GHz frequency ranges. The switches circuit will use PIN diode for the design. We will see the insertion loss, isolation & power handling. In the antenna design, we will look at some different designs on their performance such as gain, standing wave ratio & efficiency. In this project, we will use various procedures for the design from the concept to the prototypes manufacturing through RF circuitry & antenna simulations to implementations. Various procedures involved in the design of the Class A amplifier such as DC simulation, bias point selection, input and output matching circuit design and the design of a bias network are explained.
