diplexer 和duplexer的区别
录入:edatop.com 阅读:
diplexer:
it's a network that splits a signal to two or more loads, dependent
on frequency. It is the simplest form of a multiplexer, which can
split a signal into many different signal bands. Often a diplexer is used to
route signals,based on frequency, to two different receivers.
you can find it win multiband receiver (dual band cell phone?).
duplexer:
It is a three-port network that allows the transmitter and
receiver in a radar or communications system to use the same antenna. The du
plexer can be as simple as a circulator in low-power applications, or it may
be a radioactive
gas-discharge T/R tube for megawatt radars.
这两个东东在中文中怎么说呢。。。

从英文上看,前面那段一般是功分器的作用,把信号源分为多路使多路接收机共用一个信号源,但是功分器的英文应该叫power divider
后面的一个是双工器,使收发共用一个天线,典型的起器件为环型器和开关
第一个当然错了,功分器是分配功率,典型的如一分二一分四功分器,不管频率
diplexer是按照频率分配信号,最典型的例子是多个收信机共用一个天线的时候
(频分复用下),接收天线收下来的信号按照载频宽度分割给各个收信机
按照我的理解,应该称为复用器(Mutiplexer就是复用器)
第二个是双工器没错,按照道理讲,原文中似乎是不完全的,因为它只讲了时分双工
系统,duplexer另一种典型是在频分双工系统中,也是达到共用天线的作用。
