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 complex conjugate of the unmatched filter's impedance resulting in maximum power transfer
Test Circuit:
Actual matching values may vary due to PCB layout and parasitics

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. This is the complex conjugate of the unmatched filter's impedance resulting in maximum power transfer
