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 of 5 devices at room temperature 5. This is defined as the worst difference between a peak and adjacent valley within defined frequency points 6. Relative to zero dB 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 Input Power +10dBm Operation of this device outside the parameter ranges given above may cause permanent damage.
