For 433 MHz, 12.5 kHz channel, a loop filter with lower bandwidth is used to improve adjacent and alternate channel rejection. Table 13. Bill of materials for the application circuit in Figure 3 Note: The PLL loop filter component values in Table 13 (R2, R3, C6-C8) can be used for data rates up to 4.8 kBaud. The SmartRF® Studio software provides component values for other data rates using the equations on page 50. In the CC1020EMX reference design LQG15HS series inductors from Murata have been used. The switch is SW-456 from M/A-COM. |
