narrow-band-pass filter 中文意思是什麼
narrow-band-pass filter
解釋
狹通帶濾波器-
Two kinds of filters are presented : by transferring the conventional waveguide cavity filter to the siw, a narrow bandstop filter is designed and simulated, get characteristic of narrow - band bandstop filtering. for example, relative bandwidth 1. 2 %, most attenuation of 48db in band. electromagnetic bandgap ( ebg ) structures present “ forbidden band ” characteristics, siw features high - pass characteristics, so bandpass filters can be composed by combing ebg and siw
本論文提出了兩種基片集成波導濾波器結構:將傳統的腔體濾波器概念運用於基片集成波導結構,設計出了一種窄帶帶阻濾波器,對其進行模擬,得到了窄帶帶阻濾波特性,如相對帶寬為1 . 2 % ,最大衰減為48db 。 -
Applying the ways of adjusting the bandwidth, minimizing the pass band ripples and group delay ripples, a 50ghz filter is designed. in the paper, we also discuss the temperature stability of dwdm thin film narrow band - pass filter
