Notes:
1. All specifications are based on the TriQuint schematic for the main reference design shown on page 3
2. An external impedance matching network with ±2% tolerance will be necessary to achieve the proposed specifications
3. In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over
temperature
4. Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing tolerances
5. Typical values are based on average measurements at room temperature
6. These Variations are defined as the difference between the lowest loss and the highest loss within the defined frequency points
7. Measured with an RRC filtered QPSK modulated signal with a BW of 3.84 MHz place anywhere within 449 to 463 MHz
8. Relative to insertion loss at center frequency
9. This is the optimum impedance in order to achieve the performance shown
