That report indicated that there may be a hardware issue somewhere between the antenna and the amplifier.
该报告指出在天线和放大器之间的某处，可能存在硬件问题。
A uhf sensor is designed and fabricated, which mostly consists of antenna, uhf amplifier, high pass filter, and broadband wave detector.
通过与大华无线电厂合作，研制了超高频传感器，其主要由天线、超高频放大器、高通滤波器、宽带检波器等组成。
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)。
The driving amplifier enlarges signal to reach an adaptive level in order to drive the power amplifier. The enlarged signal is delivered to a filter and transmitted through an antenna.
驱动放大器放大信号到一个可以接受的输入量级以驱动功率放大器，放大后的射频信号被传送到天线分离滤波器进行滤波，最后通过天线发射出去。
If necessary, the area can be extended by adding additional repeater units, all connected to the same external antenna, using a signal splitter and line amplifier.
如有必要，该地区可以通过添加额外的扩展中继器的单位，所有连接到同一个外置天线，使用信号分离器和线路放大器。
In electronics, the degree to which the amplitude of a signal is increased when it passes through an amplifier, repeater or antenna.
在电子学中，表示信号通过放大器、增音器或天线后幅度增加的程度。
A helix antenna was presented together with low power RF amplifier, as the frequency fitted, the axial direction can obtain largest radio energy.
采用小尺寸低功耗的射频芯片结合实际环境设计出螺旋结构天线，选择合适的频率，天线在轴向方向得到最大的辐射能量。
