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. Describes the total variation over the defined frequency range 6. This is defined as the worst difference between a peak and adjacent valley within defined frequency points 7. Relative to passband loss at center frequency 8. This is the optimum impedance in order to achieve the performance shown Absolute Maximum Ratings Parameter Rating (9) o Operating Temperature -40 to +85 C o Storage Temperature -40 to +85 C o (10) Input Power (10Khrs 55 C under CW signal) +20 dBm 9. Device may operate over this range with degraded Electrical Specifications 10. Device can also meet +22dBm power for an applied CW modulated CW signal at 55 deg C for a minimum of 125 hours in the 777.0- 798.0 MHz frequency band Operation of this device outside the parameter ranges given above may cause permanent damage.
