| 摘 要： | 衰减器作为幅度调制器件被广泛用于电子战、雷达、测试设备、通信等各种微波领域。随着信息革命的深入发展,通信、雷达、测试设备等各种微波领域的电子设备趋向于小型化、低成本,对元器件的体积、功耗、可靠性、使用方便性的要求越来越高。文章介绍了一款采用GaAsPHEMT工艺和金属陶瓷贴片封装制作的L波段高精度单片六位数控衰减器的设计方法和研制结果。测试结果表明在频率为DC～2GHz内,衰减步进0.5dB,衰减范围0～31.5dB,插入损耗IL<2.5dB,输入输出驻波比VSWR<1.4,衰减精度|△A_i|<(0.2+3%A_i)dB。附加相移|△φ|<3°,控制方式为TTL电平。 |
