Abstract
A mobile radio for use in multiple different frequency plans is disclosed. The multiple different frequency plans, such as land-based plans (cellular, land mobile radio, etc.) and satellite-based plans may employ different frequency bands and, within those different bands, different frequency channel step sizes. The mobile radio employs only a single loop synthesizer to accommodate all of the different plans, including all of the different channel step sizes. It does so by employing a dynamically programmable divider circuit within the single loop synthesizer for macro-adjustment of the local oscillator frequency and a dynamically adjustable reference oscillator within the single loop synthesizer for micro-adjustment of the local oscillator frequency depending upon a recovered carrier signal.
