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=120nH L2=18nH L3=220nH L4=120nH Source/Load Impedance=50 ohm Notes - Component values may change depending on board layout. |
