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
This is the optimum impedance in order to achieve the performance shown
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 ranging from 50 to 750 ohms.
