All specifications are based on the TriQuint schematic for the main reference design shown on page 4 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. Evaluated as the total variation over the specified band 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 (8) Input Power +20 dBm 8. Input Power is targeted for an applied CW modulated RF signal at 55 C for 10,000 hours. Operation of this device outside of the parameter ranges listed above may cause permanent damage.
