All specifications are based on the test circuit shown on page 4
In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over
temperature. The guardbanded specification includes the 3 dB center frequency correlation factor between customer board and
Sawtek test fixture
Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing tolerances
All bandedge and relative attenuation measurements are referenced to the minimum insertion loss
EVM and out-of-band modulation will not be tested in production due to the complexity of test. Compliance guaranteed by design
This is the optimum impedance in order to achieve the performance shown
