耦合器将信号耦合出一部分能量，耦合出的能量常用于信号的检测或监测，比如功率测量和检波等。 通常用的耦合器是定向耦合器，定向耦合器的耦合端耦合输出是存在方向性的，如下图： 1输入时，C1端会输出信号，而C2端是隔离的；2输入时，C2端输出信号，C1 ...

在很多射频电路中，功率检测是不可或缺的，Power coupler 和Power detector 有什么区别呢？ 在很多射频电路中，功率检测是不可或缺的，Power coupler 和Power detector 有什么区别呢？Be1ednc 我们知道，任何信号都会向外辐射，只是辐射信号大小有区别而已。Be1ednc 如上图 ...

You want to join two shafts. What do you need? A coupler, of course. If the shafts don’t line up, you might consider an Oldham coupler. But what if the shafts are at a 90-degree angle to each other?

A simple workaround for all this was an acoustic coupler, a device that played your modem’s sounds directly into a phone’s receiver without any electrical connection. Modem speeds were slow ...

Unintended bucket releases are the most common incidents. Todd Petersen at the Apprentice and Skill Improvement Program (ASIP) says, “We are seeing situations where a worker is in the trench box and ...

Without significant flexibility, severe binding can occur, resulting in damage to the coupler, hitch, or trailer tongue. To prevent this type of damage, a trailer coupler must be able to conform ...
