Notes:

1.

All specifications are based on the test circuit shown below

2.

In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over

temperature

3.

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

4.

All attenuation measurements will be referenced to minimum insertion loss

5.

Total variation measured over the defined frequency range

6.

The filter can be matched for single-ended or balanced operation to an impedance of 50 Ohms to 750 Ohms
