All specifications are based on the Sawtek reference test system
In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over
temperature
Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing tolerances
Describes the minimum peak to adjacent valley variation over the defined frequency range
Referenced to minimum insertion loss
The rejection “floor” in specified ranges allows for 100KHz wide spurious responses at a max peak of 40dB below minimum
insertion loss
This is the optimum impedance in order to achieve the performance shown
