Notes: 1. Unless noted otherwise, all specifications apply over the operating temperature range with filter soldered to the specified demonstration board with impedance matching to 50 and measured with 50 network analyzer. 2. The design, manufacturing process, and specifications of this filter are subject to change. 3. Either Port 1 or Port 2 may be used for either input or output in the design. However, impedances and impedance matching may vary between Port 1 and Port 2, so that the filter must always be installed in one direction per the circuit design. 4. US and international patents may apply. 5. Electrostatic Sensitive Device. Observe precautions for handling.
