- This thesis mainly analyze the structure of switch the circuit ' s form and some of manufacturing technic . under the given frequency band , the switch has flat capability of insert loss and isolation , and can satisfy the need of millimeter - wave system
本课题主要对开关的结构、电路形式及制作工艺等方面进行了一定的分析，使得毫米波鳍线pin管开关在给定频率范围内，具有平坦的插入衰减和隔离度特性，满足毫米波系统的需要。 - Mixers are the key components of many microwave and millimeter - wave systems . the super - heterodyne receiver is always applied in modern communication system , mixer becomes the key component as is at the first part of system . but it is more and more difficult to get the choiceness lo source of the same band with the system is working at high frequency especially in the millimeter - wave . sub - harmonic mixer is a good solution to this problem now . in this circuit we need just half 、 quarter 、 even 1 / 8 of the rf signal frequency . in this paper the design and fabricate of sub - harmonic hmic mixers ( 2 , 4 ) at w - band are introduced
混频器是微波通信、射电天文学、雷达、等离子物理、遥控、遥感、电子对抗,以及许多微波测量系统中至关重要的部件。在现代通信系统中,毫米波频段通常采用超外差接收机,混频器作为第一级就成为关键部件。由于在毫米波频段,同频段高性能的本振源成本高,技术难度大,采用分谐波混频技术是解决此问题的有效途径,只需射频频率1 / 2 、 1 / 4甚至1 / 8的本振频率即可实现混频。 - An experimental setup has been designed and built up through a collaboration program between cryogenics laboratory in zhejiang university and limsi - cnrs ( france ) . the system employs the inherently reversible stirling cycle , and then its thermodynamic efficiency can easily surpass that of standing - wave system and is even comparable to that of the traditional internal combustion engines
在充分理解工作机理的基础上，与法国国家科研中心limsi实验室合作，设计并建成一台行波型热声驱动器实验装置，进行了初步实验，以氨气和氮气为工质，成功地获得了频率分别为66hz和23hz的热声振荡。 - This text is from the engineering the practical the angle that turn sets out , according to short - wave system with argus system a thought for connecting a people the correspondence negotiates , and blends oop , design a data exchange interface for first which is based on the xml , and give a the homologous engineering ascends of realize
在这个项目的初期，采用了自主研发的短波监测系统为主， argus系统为辅的协同工作的方式。本文从工程实用化的角度出发，根据短波系统和argus系统之间的数据通信协议，并融合oop的思想，设计并实现了在这两个监测系统间的基于xml的数据交换处理。 - Recent experiments have succeeded in obtaining oscillations from the new system , with frequencies of 66hz and 23hz for the cases with helium and nitrogen as the working fluids , respectively . the traveling wave system is expected to be one of the good candidates as a driver for pulse tube refrigerator , leading to a thermoacoustically driven pulse tube refrigerator without any moving component
还利用deltae对环路部分进行了数值模拟分析，着重讨论了系统的起振临界温度与临界加热功率、效率与加热温度的关系、喷射泵的作用以及不同工质(氮气和氦气)的比较等，得出一些有益的结论。
