中文摘要 | 干擾為通信電子戰的手段之一,而干擾需仰賴通信功率放大器來實現。現今戰場上的通信頻率範圍大,通信功率放大器須能具備寬頻發射能力,才能獲得顯著的干擾效果。寬頻通信功率放大器除了需要提供一個平穩功率的電磁信號,也須具備控制輸出功率大小的功能,以配合不同戰術的運用,其內部的自動位準控制(ALC)電路就顯得很重要。本文針對ALC電路的工作原理做說明,並分析傳統ALC電路功能運作,最後以實例說明ALC電路IC化之設計方式,以做為後續技術發展之參考。 |
英文摘要 | Jamming is one of the methods used in communication electronic warfare which should be relied on power amplifier to accomplish this task. Because of the communication frequency range of the battlefield is very wide; the power amplifier needs to possess the ability of broadband jamming to achieve obviously jamming effect. Broadband power amplifier needs not only providing a stable power signal but also the function of power level control to fit different tactics applications. Therefore the automatic level control (ALC) circuit becomes very important. This article describes the operating theorem of the ALC circuit, the analysis of traditional ALC circuit operation function, and the practical ALC circuit digitized design way for the reference of the follow up technical development. |
