查询词典 duplexer

Tofind a target and determine its position,any radar station has to basically consist of a transmitter,a receiver,an antenna,an antenna duplexer,a display and a timer.

为了要发现目标和确定其位置，任何雷达站基本上都必须包括发射机、接收机、天线、天线转换开关、显示器和定时装置。

A controller processes the RF signals received at and transmitted from the duplexer and controls the whip antenna driver to extend the whip antenna in a speech state or upon a call attempt from a user.

控制器处理从双工器接收的RF信号和发送到双工器的RF信号，控制拉杆天线驱动器，以便在谈话状态下或一旦用户尝试呼叫时，伸出拉杆天线。

SCR-521. The most significant improvement in the ASE was the useof an antenna duplexer, which permitted the use of just one send-receive antenna, rather than two separate units.This yielded appreciable improvement in aircraft performance because of drastically reduced wind drag.

ASE上最重大的改进的使用了天线双工机，使得可以只使用一个收发天线而不是两个，这使飞行时的风阻明显减少，飞行性能得到显著的提高。

Thus, we can apply the very algorithm to make their numerical analysis much quickly and precisely. We will take the following two devices, the multiple branch rectangular waveguide directional coupler and the H-plane T-junction duplexer, as examples, systematically analyze and discuss the "Network segment and de-segment algorithm" presented and GA application in the computer aided design of complex microwave structures.

本论文将以矩形波导分支电桥耦合器和H面T型接头双工器的优化设计为例，比较系统地分析讨论将&多模网络分解—重组算法&和遗传算法应用于微波电路器件CAD的理论、算法和计算技术问题，并给出主要的器件性能特性曲线，以全面报告我们研究工作的心得体会和研究成果。

We have ten main patent rights about SAWF, such as low-loss surface wave intermediate frequency filters and surface acoustic wave duplexer for wireless telephone.

Four new microwave devices revolutionized radar; the British Magnetron (optimized and fanned out into a family by BTL/Western Electric), the American gas discharge duplexer transmit-receive T-R switch tube, the American advanced semiconductor mixer diode (MIT Rad Lab and BTL/WE), and the American klystron local-oscillator tube.

四种新型的微波装置掀起了雷达发展的革M：英国磁控管（为贝尔电话实验室和Western Electric所改良并发展成为一个大家族），美国的气态双工收发转换开关，美国的先进半导体二极管混频器(MIT 电子实验室和 BTL/WE)和美国的可调速本机振荡管。

Tune-up was simple: The transmitter was peaked up, then the duplexer was first adjusted by watching the spark gap (with the receiver disconnected; it was too easy to fry the receiver pre-amplifier), then the receiver was tuned up, usually on a handy neighboring target.

接着调整接收器，通常都是随便找个附近的目标。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
