All specifications are based on the test circuit shown;
In production, all specifications are measured by Agilent Network analyzer and full 2 port calibration at room
temperature;
Electrical margin has been built into the design to account for the variations due to temperature drift and
manufacturing tolerances;
This is the optimum impedance in order to achieve the performance show.
