(1) Single ended output power obtained after de-embedding microstrip trace losses and matching with a manual tuner. Unused port terminated to 50-Ω load.

(2) Output power, spurs, and harmonics can vary based on board layout and components.

(3) Single-ended AC coupled sine wave input with complementary side AC coupled to ground with 50-Ω resistor.

(4) For lower VCO frequencies, the N divider minimum value can limit the phase-detector frequency.

(5) The PLL noise contribution is measured using a clean reference and a wide loop bandwidth and is composed into flicker and flat components. PLL_flat = PLL_FOM + 20 x log(f_VCO/f_PD) + 10 x log(f_PD/1 Hz). PLL_flicker (offset) = PLL_1/f + 20 x log(f_VCO/1 GHz) - 10 x log(offset/10 kHz). Once these two components are found, the total PLL noise can be calculated as PLL_Noise = 10 x log(10^PLL_Flat/10 + 10^{PLL_flicker/10}).
