To design flat scattering parameters at 434 MHz frequency region by using AWRP

Abstract

In this study, an Ultra High Frequency (UHF) flat gain power amplifier which has 434 MHz centre frequency and 12 MHz bandwidth frequency is designed. The main purpose of the work is to design and obtain flat scattering parameters and the other figure of merit at these frequency values. Approximately 4 MHz flatness from 432 MHz to 436 MHz at gain characteristics has been obtained by using Microwave Office AWRP (Applied Wave Research Program) supported by National Instruments. Limitation borders have been put to the graph and other optimization techniques are used on the program so that the gain graph becomes flat along 4 MHz at the peak side. Efficiency and linearity are also examined but the flatness is the main object for this project.
