Step Response of Marki Microwave Bias Tees

BT-0040 Rise Time

Recently a customer asked what the settling time of the DC port on our surface mount bias tees was. Settling time is a tricky spec. When you apply a DC voltage to the bias tee, you want it to show up at your device immediately so you can do whatever it is that you need to do. Conversely, you don’t want any high frequency noise from the DC line contaminating your bias, so we try to make the DC to common port isolation high down to low frequencies.
