All specifications are based on the test circuit shown below
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 manufacturing tolerances
Relative to insertion loss at 183.6 MHz
This is the complex conjugate of the unmatched filter’s impedance resulting in maximum power transfer
