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