TE01 94 GHz 磁旋行波放大器之穩定度分析

Abstract

本論文以數個數值模擬程式計算TE01(1)磁旋行波放大器各可能起振模之起振電流，並利用高電阻率材質抑制自發震盪的特性，設計一個運作於94 GHz之高增益磁旋行波放大器。據此，本論文提出一藉由TE01(1)模態運作於93.6 GHz之磁旋行波放大器，其峰值輸出功率為52.4千瓦，此時出入功率為0.792毫瓦，具有78dB之增益。

This thesis uses several simulation programs to calculate the start-oscillation current of possible oscillation modes of a TE01(1) gyro-TWA, and proposes a design utilizing the distributed loss section to suppress possible self-oscillations, achieving high gain near 94 GHz. A 93.6 GHz gyro-TWA operating by TE01(1) is designed. The peak power is 52.4 kW, when the input power is 0.792 mW, with a gain of 78 dB.
