程控步进衰减器在通信测试设备上的设计应用

Design and Application of Programmable Step Attenuator in Communication Test Equipments

程控衰减器的信号调节和电平控制功能可广泛应用于通信测试设备中,而利用HMC472LP4E单片集成衰减器设计的一款宽带程控步进衰减器,更具有较大的动态衰减范围、优良的衰减精度等优点。

Signal program-controlled attenuator regulation and level control function can be widely used in communications test equipment.Now,a new wideband programmable step attenuator,designed by monolithic integrated attenuator with MMIC HMC472LP4E,has advantages of larger dynamic attenuation range and excellent attenuation accuracy and so on.
