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 are measured relative to minimum insertion loss 5. This is the optimum impedance in order to achieve the performance shown Test Circuit: Actual matching values may vary due to PCB layout and parasitics 50 Ω Single-ended 1,2,3,4,6,7,8,9 50 Ω 33pF 10 5 18nH 50 Ω 47nH 47pF |
