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 L2 C1 C2 L1=27nH L2=27nH C1=10pF C2=10pF Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
