1. Coupling capacitors at input and output are recommended for use in applications that require DC isolation of input to output port or either port to ground.
Alternatively, if DC pass IN - OUT is required, use the “D” version of this model which will support DC IN-OUT, and provide >100 MOhm isolation to ground.
* Passband rating, derate linearly to 3.5W at 100°C ambient.
Permanent damage may occur if any of these limits are exceeded.
