Design and Fabrication of An LNA for The Reception of The Ku-Band Satellite Broadcast Signals
Ku-대역 위성 방송 수신 시스템을 위한 저잡음 증폭기의 설계 및 제작
Abstract
In this paper, a low-noise amplifier is designed and fabricated using the HJFET for the reception of the Ku-band satellite broadcast signals. The optimum input and output reflection coefficients of each amplifier stage are obtained by the trade-off between the stable gain and the noise figure circle. The amplifier performance is simulated and optimized using a microwave CAD software. The designed amplifier is fabricated and tested. Results of the test show a gain of 17.0 dB, a gain flatness of less than
