| Summary: | This project
investigates the characteristics of
three
types of
Power Amplifier (PA)
circuit that will use in the Software Defined Radio (SDR). The circuits are Conventional
PA, the proposed PA using NPN transistor, and the proposed PA using NMOS
transistor. In additio
n, the circuit will be constructing with efficiency
-
boosting technique
circuit that is using Doherty Amplifier. The simulation of the circuit will be done by
using the PSpice version 9.2 simulation software. The analysis will be done by
manipulating the op
erating frequency that is suitable for Global System for Mobile
Communication (GSM) application. The comparison that will be analyzed is the
efficiency of the circuit and the output gain. The
outcome of the results shows
that the
PA circuit using the NMOS t
ransistor give high efficiency and gain.
With the addition of
the Doherty amplifier also has increased the performance of the circuit. |
