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. MAXIMUM RATINGS Operating temperature -55°C to 100°C Storage temperature -55°C to 100°C RF Power Input3 TYPICAL FREQUENCY RESPONSE Ratings 10 W max. at 25°C 3. Passband rating, derate linearly to 3.5W at 100°C ambient. Permanent damage may occur if any of these limits are exceeded.
