Power Handling

Maximum power handling is a common concern of our customers. Nothing is worse than plugging in an expensive device only for it to be immediately destroyed. Understanding power handling is important to us as well so that we can address customer concerns about reliability and to develop devices that are able to tolerate higher power levels. The purpose of this document is to describe the failure mode and maximum power handling of several Marki Microwave product lines. It lists the power required to destroy the device and describes what part of the device fails at that power.

Step Response of Marki Microwave Bias Tees

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.
