All specifications are based on the TriQuint schematic for the main reference design shown on page 3 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. Relative to insertion loss at center frequency 6. Amplitude Variation is defined as the difference between the lowest loss and the highest loss within defined frequency points 7. This is the optimum impedance in order to achieve the performance shown Absolute Maximum Ratings Parameter Rating o Operating Temperature -40 to +85 C o Storage Temperature -40 to +85 C Operation of this device outside the parameter ranges given above may cause permanent damage.
