All specifications are based on the test circuit shown below In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over temperature Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing tolerances Relative to minimum insertion loss Sawtek’s production specifications reflect the typical performance in a 50 Ohm single-ended system. This filter can be used in both single-ended and/or differential modes at each port. In addition, similar performance can be achieved in source and load impedances of 200 Ohms.
