All specifications are based on TriQuint 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 temperature drift and manufacturing tolerances
Typical values are based on average measurements at room temperature
Describes the total variation over the defined frequency range
Power handling is targeted for an applied CW modulated RF signal at 55 oC for 10,000 hours. The filter is also able to sustain an
instantaneous 20dBm signal without decay
This is the optimum impedance in order to achieve the performance shown
