Examples
- High level signal
高电平信号 - The lna is one of the most important and broad components in microwave communication system receiver , and is used to amplify the low level signal . as the first signal processing block after the antenna , the lna determines the noise figure and input voltage swr and greatly impacts the dynamic range
低噪声放大器( lna )广泛应用于微波接收系统中，是重要器件之一，主要用来放大低电平信号，由于是自天线下来第一个进行信号处理的器件， lna决定了整个系统的噪声性能和电压驻波比vswr ，并对动态范围有着较大的影响。
