摘　　要：幅度平坦度是发射信道的一个重要指标,它直接影响接收信道的灵敏度。该文对某超宽带离散发射信道进行了分析和研究,设计了高精度阻抗耦合电路。它具有结构简单和插入损耗低的特点,试验验证了能将信道的幅度平坦度由3dB改善至1.5dB。Amplitude flatness is an important indicator of transmission channel,which directly affects the sensi- tivity of the receiver channel. One ultra-wideband discrete transmission channel was analyzed and studied, and high- precision impedance coupling circuit was designed. It had the characteristics of simple structure and low insertion loss. The experiment proved that it could improved the flatness of the channel from 3 dB to 1.5 dB.
