1. 2. 3. 4. 5. 6. 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 Referenced to the minimum insertion loss of the device. Amplitude ripple will measure the worst case peak to adjacent valley within the specified frequency points This is the optimum impedance in order to achieve the performance shown
