Notes:
1. 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=68nH L3=27nH
L2=15nH L4=82nH
Source/Load Impedance=50 ohm
Notes - Component values may change depending on board layout.
