IDT新推数字步进衰减器(DSA),扩展其无线通信产品系列。该DSA使客户能简化软件接口、提高可靠性并防止损坏昂贵的子组件。可在蜂窝基站和其他应用中,将瞬态振铃降低多达95%
衰减器中吸收片的材料一般是什么?各个参数呢?
Calculates the resistor values, attenuation, ’impedance’, reflection coefficient, VSWR and return loss of a Pi attenuator. This can be built into a FLEXI-BOX, and a transmission line PCB is available which easily adapts for this circuit with one simple trimming operation. There is also a selection of suitable RF connectors available.
