All specifications are based on the test circuit shown; 2. In production, all specifications are measured by Ag ilent 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.
