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
All attenuation measurements will be referenced to minimum insertion loss
Total variation measured over the defined frequency range
The filter can be matched for single-ended or balanced operation to an impedance of 50 Ohms to 750 Ohms
