Even though the device (DUT) is rapidly varying from standby mode (low current) to the RF transmit state (high current), they are also capable of providing stable voltage output.
即使待测器件(DUT)从待机状态(低电流)到射频发射状态(高电流)进行快速跳变，它们也能够提供稳定的电压输出。
In the transmit direction, the transceiver provides RF signals to the power amplifier, which amplifies the signals based on gain and ramp information for a given modulation type.
在发送方向，收发信机向功率放大器提供射频信号，功率放大器根据给定调制类型的增益和斜坡信息对信号进行放大。
The ML7338(ARM7TDMI core) and RF module RDA5206 are used to demodulate RF signals, recode, remodulate and transmit baseband signals, thus solving the RF interference problem in traditional stations.
该系统主要采用小灵通基带芯片ML7338（ARM7TDMI核）和RDA5206射频模块，实现对射频信号的解调，同时对基带信号重新编码再调制发射，很好地解决了普通直放站射频干扰问题。
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)。
