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 zero dB. 6. This is the optimum impedance in order to achieve the performance shown Absolute Maximum Ratings Parameter Rating (7) o Operating Temperature -55 to +85 C o Storage Temperature -55 to +85 C (8) Input Power +15 dBm 7. Device may operate over this range with degraded Electrical Specifications 8. Device is measured for equivalent 10K hours +85 C CW Signal Operation of this device outside the parameter ranges given above may cause permanent damage.
