(1) For lower VCO frequencies, the N divider minimum value canlimit the phase-detector frequency.
(2) Single ended output power obtained after de-embeddingmicrostrip trace losses and matching with a manual tuner. Unused port terminated to 50-Ωload.
(3) The PLL noise contribution is measured using a clean referenceand a wide loop bandwidth and is composed into flicker and flat components. PLL_flat = PLL_FOM + 20× log(Fvco/Fpd) + 10 × log(Fpd / 1Hz). PLL_flicker (offset) = PLL_1/f + 20 × log(Fvco / 1GHz) – 10× log(offset / 10kHz). Once these two components are found, the total PLL noise can be calculatedas PLL_Noise = 10 × log(10 PLL_Flat / 10 + 10 PLL_flicker /10 )
(4) Output power, spurs, and harmonics can vary based on boardlayout and components.
