Notes:

1.

All specifications are based on the test circuit shown below

2.

This specification is valid for room temperature only. The specification over the full temperature range(s) is available on the next

page(s)

3.

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

4.

This is the maximum peak to adjacent valley amplitude change in passband

5.

This is the optimum impedance for maximum power transfer

Test Circuit:

Actual matching values may vary due to PCB layout and parasitics
