Design and Implementation of High Gain High Stability Power Amplifier for X band Radar Transmitter

Abstract

Power Amplifier (PA) is an important part of transmitter’s front end. The main function is to amplify extremely high gain high stability power amplifier for radar transmitter. In this paper, PA used in transmitter portion of radar is designed and implemented. DC biasing, stability checking and input/output impedance matching of the RF transistor design procedures are considered. The stability analysis of power amplifiers is one of the most critical and the most challenging aspects of power amplifier design. Stability analysis is shown an analysis technique, which accurately predicts the oscillations in power amplifiers. The power amplifier (PA) design project is simulated with Electronic Workbench Multisim8 software. The simulation results are considered on the frequency used in 9.35GHz of X-band
