发明名称 Multiband frequency generation using a single pll-circuit
摘要 To minimize the overall circuitry necessary in a multiband frequency generator, output terminals of a voltage-controlled multiband oscillator (22-1, ..., 22-N) are coupled to a frequency synthesis unit (10) via a frequency selective coupling unit (24). The frequency synthesis unit (10) derives a phase difference between a frequency control input signal and the output signal of the frequency selective coupling unit (24) to control the voltage-controlled multiband oscillator (22-1, ..., 22-N).
