Notes:
1. All specifications are based on the 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. Typical values are an average of 12 pieces measured at room Temperature
5. Amplitude Ripple is defined as the worst case difference between a peak and an adjacent valley within defined frequency points
6. Relative to insertion loss at center frequency
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
