All specifications are based on the test circuit shown on page 3. 2. In production, devices will be tested at room temperature to a guard-banded specification to ensure electrical compliance over temperature. 3. Electrical margin has been built into the design to account for the variations due to manufacturing tolerances. 4. Variation is defined as the total peak to peak variation over the defined frequency range. 5. Measurement made with a RRC filtered QPSK modulated signal. 6. Measurement made only during engineering development. 7. Measurement made relative to insertion loss at Center Frequency, F 0. Data Sheet: Rev.
