Chapter 10. Integer-N Frequency Synthesizers > General Considerations
10.1. General Considerations
Recall from Chapter 3 that each wireless standard provides a certain number of frequency channels for communication. For example, Bluetooth has 80 1-MHz channels in the range of 2.400 GHz to 2.480 GHz. At the beginning of each communication session, one of these channels, fj, is allocated to the user, requiring that the LO frequency be set (defined) accordingly (Fig. 10.1). The synthesizer performs this precise setting.
