微波反饋放大器的匹配和增益帶寬的探討
RESEARCH ON MATCHING AND GAIN-BANDWIDTH OF MICROWAVE FEEDBACK AMPLIFIER
-
摘要: 本文介紹了小信號微波反饋放大器的分析與綜合。放大器采用通常的增益級框圖表示和并聯(lián)反饋。文中提供了全部網(wǎng)絡(luò)元件的估算值和閉環(huán)寬頻帶增益、帶寬和雙端口的匹配值。用圖解法對匹配值與增益進行了權(quán)衡。最后用實例描述了綜合方法。

Abstract: Small signal analysis and synthesis of a microwave amplifier with shunt feedback are described. The estimation values of all network elements, the closed-loop broadband gain, bandwidth and match quality of both ports are given. The relation between the match quality and gain is studied by graphic method. -
