Notes:
1. All target specifications are based on TriQuint test circuit shown below
2. All target specifications represent a design goal and not a guarantee until the design is finalized and a datasheet is issued
3. In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over
temperature
4. Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing tolerances
5. Typical values are based on average measurements at room temperature
6. Attenuation relative to Maximum Insertion Loss
7. This is the optimum impedance In order to achieve the performance shown
Test Circuit:
Actual matching values may vary due to PCB layout and parasitics
