1. 2. 3. 4. 5. 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 and manufacturing tolerances All attenuation measurements are measured relative to minimum insertion loss This is the optimum impedance in order to achieve the performance shown
