The main work of the system can be divided into four main parts as the following : ( 1 ) 10. 5ghz bandpass filter the main contradiction of filter is caused by its function of dividing frequencies. in order to properly divide frequencies, not only need passband ’ s attenuation to be as small as possible and stopbands ’ as big as possible, but also need a sharp and quick change between the attenuation of passband and stopband, thus to make their diversity obvious
這四個功能模塊分別是: (一) 10 . 5ghz帶通濾波器濾波器的主要矛盾是由它分隔頻率的功能決定的,為了使分隔理想,一方面要求通帶的衰減盡可能小,阻帶衰減盡可能大,亦即通帶和阻帶的衰減差值要盡量大;另一方面要求通帶和阻帶之間衰減的變化應盡可能快,最好是陡峭的跳變,使阻帶和通帶的分隔十分明顯。The usual method to broaden the bandwidth of the pin diode switch is combining the pin diodes with stub filters : when under reverse bias, the didoe is part of the filter, the transmission bandwidth is broadened ; when under forward bias, the structure of the filter is destroyed, signal is isolated
Pin二極體開關展寬頻帶的方法一般是把pin二極體結合進短截線濾波器,使pin二極體在反向偏置時作為濾波器的組成部分,以展寬開關在傳輸狀態下的頻帶;當二極體正向偏置的時候,濾波器的結構被破壞,起到隔離的作用。At the same time, the design of cascaded coupler with a given ratio distribution is proposed, which can lead to higher isolation by suppressing sidelobe. 2. according to theoretical analysis and numerical simulation, the interleaver can show flat - top and high isolation pass band characteristic when the two couplers " ratio is assigned to 15 percent
2 .對全光纖反射式奇偶交錯濾波器進行了理論分析和數值模擬,發現當兩個耦合器的分光比均為15時產生了平頂高隔離度的通帶頻響特性,做了相關實驗,結果與理論分析基本符合。
