南京电子器件研究所研制成功了ＷＳＢ１００１型吸收式低相移电调衰减器。研制中提出了一种简便的实现低相移的方法。将衰减器与移相器技术结合起来，通过计算机优化设计，保证了衰减器在偏置电流加大、衰减量连续增加下，在整个动态范围内，任意态相对初始态的相位变化很... Nanjing Institute of Electronic Devices successfully developed WSB1001 type absorption phase shift attenuator low phase shift. In the development of a simple method to achieve low phase shift. The combination of attenuator and phase shifter technology, through the computer optimized design, ensures that the attenuator will change its phase relative to the initial state under any dynamic range over the entire dynamic range with increasing bias current and increasing attenuation. .
