Abstract
A communication device (300) having a synthesizer (304) for synthesizing a radio frequency signal. The synthesizer (304) includes a first and a second mode of operation with the first mode having a wider bandwidth loop than the second mode. An amplifier (316) is included for amplifying the radio frequency signal of the output of the synthesizer (304). The amplifier (316) is turned on during the first mode of operation of the synthesizer (304) for minimizing the frequency pull of the radio frequency signal.
