摘　　要：以收发组件为应用背景,发现基于氮化铝陶瓷基板的射频电路导致射频信号拖尾,而射频信号拖尾时间直接影响接收通道限幅恢复时间,进而严重影响收发系统的接收灵敏度。研究发现氮化铝陶瓷是一种压电半导体材料,在射频信号传输过程中会产生压电效应,进而导致射频信号拖尾,传输功率越大产生的压电效应越强、射频信号拖尾时间越长。研究成果对于大功率收发组件电路基板选用具有理论指导意义和工程应用价值,特别是在高精测高、超近测距等雷达应用领域。Based on the application background of transceiver module,it is found that RF circuits based on aluminum nitride(AlN)ceramic substrates cause RF signal tailing,and the RF signal tailing time directly affects the limited amplitude recovery time of the receiving channel,thereby seriously affecting the receiving sensitivity of the transceiver system.It is found that AlN ceramics are piezoelectric semiconductor materials that generate piezoelectric effect during RF signal transmission,leading to RF signal tailing.The higher the transmission power,the stronger the piezoelectric effect and the longer the RF signal tailing time.The research results have important theoretical guidance significance and engineering application value for the selection of high-power transceiver module circuit substrates,especially in radar application fields such as high-precision height measurement and ultra-close range measurement.
