All specifications are based on the test circuit shown 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. This is the optimum impedance in order to achieve the performance show Matching Configuration OUTPUT 50Ω INPUT 50Ω L1=L2=82nH L1 Source/Load Impedance=50 ohm L2 Notes - Component values may change depending on board layout.
