Abstract
A frequency synthesizer, especially for mobile radio base stations, transforms a digital input signal having a first frequency rapidly into a digital output signal having a second frequency. Similar to an N-fractional synthesizer, in the frequency synthesizer, the digital input signal is fed to a series connection having a phase detector, a filter and a voltage-controlled oscillator. The conventional N/N+1 divider provided in the feedback path, as in an N-fractional synthesizer, is replaced by some sort of digital synthesizer that is clocked or supplied with the digital output signal that is produced by the voltage-controlled oscillator.
