A low phase noise, wideband, mm-wave, integer-N PLL that is capable of supporting an 802.15.3c heterodyne transceiver is reported. The PLL can generate 6 equally spaced tones from 43.2 GHz to 51.84 GHz, which is suitable for a heterodyne architecture with ${rm F}_{rm LO}=(4/5)times{rm F}_{rm TRX}$. Phase noise is measured directly at the ${rm F}_{rm LO}$ frequency and is better than $-$97.5 $~$dBc/Hz@1 MHz across the entire band. The reported frequency synthesizer is smaller, exhibits less phase noise, and consumes less power than prior art. In addition, the ${rm F}_{rm LO}$ tone corresponds to the fundamental of the VCO as opposed to a higher harmonic.
