Single ended output power obtained after de-embedding microstrip trace losses and matching with a manual tuner. Unused port terminated to 50-Ω load.
Output power, spurs, and harmonics can vary based on board layout and components.
Single-ended AC coupled sine wave input with complementary side AC coupled to ground with 50-Ω resistor.
For lower VCO frequencies, the N divider minimum value can limit the phase-detector frequency.
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(fVCO/fPD) + 10 x log(fPD/1 Hz). PLL_flicker (offset) = PLL_1/f + 20 x log(fVCO/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(10PLL_Flat/10 + 10PLL_flicker/10).
See Section 7.3.7.1 for details.
