2.4GHz to 2.5GHz 802.11g/b
RF Transceivers with Integrated PA
Calculating Integer and Fractional Divider Ratios
The desired integer and fractional divider ratios can be
calculated by dividing the RF frequency (f RF ) by f COMP .
For nominal 802.11g/b operation, a 40MHz reference
oscillator is divided by 2 to generate a 20MHz compari-
son frequency (f COMP ). The following method can be
used when calculating divider ratios supporting various
reference and comparison frequencies:
LO Frequency Divider = f RF / f COMP = 2437MHz /
20MHz = 121.85
Integer Divider = 121 (d) = 0111 1001 (binary)
Fractional Divider = 0.85 x (2 20 - 1) = 891289 (decimal)
= 1101 1001 1001 1001 1001
See Table 13 for integer and fractional divider ratios for
802.11g/b systems using a 20MHz comparison frequency.
