1. All specifications are based on TriQuint 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. Referenced to minimum insertion loss
5. The rejection “floor” in specified ranges allows for 100KHz wide spurious responses at a max peak of 40dB below minimum
insertion loss
6. This is the optimum impedance in order to achieve the performance shown
