Notes:
1. In Applications where DC isolation to ground is required, coupling capacitors are recommended to avoid DC leakage. 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.
3. Passband rating, derate linearly to 3W at 100C ambient. Permanent damage may occur if any of these limits are exceeded.
