收发器

The main parameters for the reception path is a very low noise figure (2dB typical including the duplexer and the limiter losses), the amplitude/phase control with a very high accuracy.

接收支路的主要参数是很低的噪声系数(典型值是2dB，包括收发开关和限幅器损耗)，以及很高精度的幅相控制。

The "main frame" unit on board ships contains the timer, transmitter, receiver, power supply and transmit-receive "duplexer" function of the antenna system.

计时器则通常包含在舰艇的&主机&里，发射机，接收器，动力供应以及收发双工功能位于天线系统。

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。

The article introduces communication theory of FM at first, recommend one more pair of sound receive the basic operation principle of telephone transmitter MT8888C and commonly used work pattern frequently more, then regard realizing receiving and dispatching DTM F signal as the typical interface circuit that the example provides MT8888C and 89C51 and control the software.

文章首先介绍了FM的通信理论，再介绍双音多频接收发送器MT8888C 的基本工作原理和常用的工作模式，然后以实现收发DTM F 信号为例给出了MT8888C 与89C51 的典型接口电路和控制软件。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
