matching impedance

基本解释

In microwave circuit and aerial system, impedance matching is very important.
在微波电路和天线系统中，阻抗匹配是十分重要的问题。
The matching impedance and wastage relate to the TWT can or can not work up to snuff. They are the problems which need be solved when we design the input and output apparatus.
其中，输入输出端口的阻抗匹配和损耗问题关系到行波管能否正常工作，是设计输入输出耦合装置时需要解决的问题。
The small-size wide-band antenna (103) further includes a stub conductor (17) as an impedance matching unit for matching the impedance between the radiation element and the power supply means.
小型宽带天线（103）还包括作为在辐射元件和电力供应单元之间进行阻抗匹配的阻抗匹配单元的短截线导体（17）。

Even with distributed elements of what appears t be a miniature LOG PERIODIC antenna will have some difficulties with proper impedance matching, ohmic losses and inductance issues to say the least.

Since most commercial (COTS) devices for the radio communications industry are normally 50 ohms intrinsic impedance, there will be problems with proper matching of the main power amplifier and the receiver front end.
