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 based on average measurements at room temperature
5. 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

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 based on average measurements at room temperature
5. Relative to insertion loss at 70MHz
6. Passband Ripple is defined as the worst case peak to adjacent valley within the passband. The edge of the passband is the point
where the amplitude begins a downward trend that does not reverse until the stopband
7. This is the optimum impedance in order to achieve the performance shown
