Antenna and antenna amplifier的意思|示意

This paper introduces the working principle of the two-tube antenna amplifier, expounds the maintaining methods for the antenna amplifier, and points out some common faults of the antenna amplifier.

在介绍两管天线放大器工作原理的基础上，对天线放大器的检修方法作了阐述，并对天线放大器常见的故障进行了概括。

This is fortunate, since most RF paths are duplex (bidirectional) channels with a need for signals to go from antenna to front end (receive mode) and from power amplifier to antenna (transmit mode).

这是幸运的，因为大多数RF路径是双工(双向)通道需要的信号从天线到前端(接收模式)和功率放大器天线(发射模式)。
