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 L1 INPUT 50Ω L1=L2=47nH L2 OUTPUT 50Ω C1=82pF C2=56pF Source/Load Impedance=50 ohm C1 C2 Notes - Component values may change depending on board layout.
