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

Source/Load Impedance=50 ohm

Notes - Component values may change depending

on board layout.
