| 1. | 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 |
| 2. | 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 |
| 3. | 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。 |
| 4. | 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。 |
| 5. | 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 。 |
| 6. | 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。 |
| 7. | 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 |
| 8. | 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。 |
| 9. | 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。 |
