Notes:
1. All specifications are based on the test circuit shown below. Testing is carried out using test fixture 971748, test data sheet
122288-02, to equipment specification 100221.
2. In production, devices will be tested at room temperature in a Sawtek test fixture 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. Maximum peak to adjacent valley over the defined frequency range.
5. This is the optimum impedance in order to achieve the performance shown.
