Notes:
1. In applications where DC voltage is present at either input or output ports, coupling capacitors are required. Alternatively, if DC pass IN-OUT is required, Mini-Circuits D suffix version of this model will support DC IN-OUT, and provide >100 MOhm isolation to ground.
2. Measured on Mini-Circuits Characterization Test Board TB-270.
