Notes:

1.

All specifications are based on the test circuit shown below

2.

This specification is valid for room temperature only

3.

Electrical margin has been built into the design to account for the variations due to manufacturing tolerances

4.

All attenuation measurements are measured relative to minimum insertion loss

5.

This is the optimum impedance in order to achieve the performance shown
