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 shown Matching Configuration L1 C1 L2 L1=33nH L2=22nH C1=82pF C2=36pF C2 Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout.
