3 high frequency signal low insert loss , high isolation , high flatness index inside 3高频信号插入损耗低隔离度高带内平坦度指标高
The study of muffier ' s insert loss based on gt - power with parallel of expansionary insert - pipe inside of two rooms 的并联内插管双室扩张式消声器插入损失研究
Insert loss of the mems shatter will be no more than 3db in the whole frequency and the phase shifter is 25 Sf纠。 o器,所有弹州段完好振动的寿命为3x10 ‘次。
At present the equation of insert loss hasn ' t indicated the effect of absorption , only refers to the effect of sound insulation 摘要目前对声屏障的插入损失计算所用的公式,没有体现材料吸声对绕射声衰减的作用。
This passive circuit exhibits a measured 2db insert loss and 11db return loss . also , the theory of 3db power splitter is described 实测结果表明经过改进的功率分配/合成网络在30 . 53ghz到39ghz范围内损耗小于2db ,回波损耗优于10db 。
In contrast with the conventional filters , hts filters provided many advantages , such as much less insert loss , more steep edge , smaller size and easier integration 相对于传统滤波器,高温超导滤波器具有带内插损小,带边陡峭,体积小、易于集成等优点。
At the same time , we have manufactured a transition from microstrip line to rectangle waveguide , working in full ka - band . the insert loss of a single transition is between 0 . 25db and 1db 同时,完成了ka全频段微带波导过渡的研制,在26 . 5 39 . 5ghz频率范围内,单个微带波导过渡的插损在0 . 25 1db
In 32ghz ~ 37ghz , the insert loss is about 0 . 2db . in the millimeter - wave system which chiefly using waveguide as transmission line , the transition between waveguide and microstrip is absolutely necessarily 其特点除了损耗低外,无需阻性材料,制作工艺简单,可以在常用的软基片上做出高性能的功率分配、合成网络,值得推荐。
In the paper , the transition of ka band rectangular waveguide to micro strip probe and the back - to - back structure are designed . the measurement results indicated the low insert loss and low return loss from 35 ghz to 40 ghz 本文设计了ka波段矩形波导到微带探针过渡结构以及背对背结构,测试结果表明,在35 40ghz频率范围内,其插入损耗和回波损耗都比较小。
