Notes:
1. All specifications are based on the test circuit shown below
2. In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over
temperature
3. Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing tolerances
4. All attenuation measurements will be referenced to the insertion loss at center frequency
5. Total variation measured over the defined frequency range
6. This is the optimum impedance in order to achieve the performance shown
