Notes:

1. All specifications are based on the test circuit shown;

2. In production, all specifications are measured by Agilent Network analyzer and full 2 port calibration at room

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.
