(1) In Application 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.
