초록
Gauss-Jacobi relaxation 方法으로부터 非線形 마이크로波 回路解析 알고리듬을 薄出하고, Harmonic Balance 技法을 應用하여 갈륨비소 쇼트키 障壁 다이오드를 이용한 混合器의 非線形 및 線形 回路解析 方法을 提示하였다. 本 硏究에서의 解析方法으로부터 마이크로波 混合器의 變換損失을 正確히 豫測하고, 컴퓨터 시뮬레이션으로부터 MMIC設計에 有用함을 보였다. 寬察로 Ku-밴드用 混合器를 MIC로 設計, 製作하여 시뮬레이션 結果의 妥當性을 立證하였다.
A technique is suggested which enables the large signal current and voltage waveforms to be determined for a GaAs Schottky-Barrier diode mixer by extracting the algorithm for the nonlinear circuit analysis from the Gauss-Jacobi relaxation and the application of the Harmonic Balance Technique. Both the nonlinear and linear steps of the analysis are included. This analysis permitts accurate determination of the conversion loss for microwave mixer and the computer simulation provides an method applicable to MMIC design. The validity of the nonlinear and linear analysis is confirmed by comparing the simulation results with experimental data of the conversion loss.
