Abstract

In this paper, K-band multi-channel receiver was designed and fabricated for low noise amplification and down conversion to L-band. The fabricated multi-channel receiver incorporates GaAs-HEMT LNA(Low noise amplifier) which provides less than a 2 dB noise figure, IR(Image Rejection) Filter for rejection of image frequency, IR(Image rejection) mixer to reject a image frequency and improve an IMD(Intermodulation Distortion) characteristic. Test results of the fabricated multi-channel receiver show less than a 3.8 dB noise figure, conversion gain of more than 27dB, and IP1dB(Input 1dB Gain Compression Point) of -9.5 dB and over.

본 논문에서는 K대역의 신호를 수신하여 저잡음 증폭 및 L대역으로 하향 변환하는 다채널 전단 수신기를 설계 및 제작하였다. 제작된 다채널 전단 수신기는 잡음지수 2.3 dB 이하의 특성을 가지는 GaAs-HEMT 기반의 저잡음 증폭소자, 이미지 성분의 억제를 위한 IR(Image Rejection) Filter, 이미지 성분 억제와 IMD (Intermodulation Distortion) 특성 개선을 위한 IR(Image rejection) 믹서를 포함한다. 제작된 다채널 전단 수신기의 시험결과, 3.8 dB 이하의 잡음지수와 27 dB 이상의 변환이득을 가지며 입력신호 기준 -9.5 dBm 이상의 P1dB(1dB Gain Compression Point) 특성을 나타내었다.
