Fractional Phase Noise At 3532.9 Mhz - Texas Instruments TRF3722EVM User Manual

Phase Noise Validation - Integer Mode
7. TRF3722 phase noise at 3532.9-MHz frequency at LO_OUTP is shown in
8. To obtain optimum phase noise performance use linear clean power supplies at TP3 3.3-V DC supply
and TP4 5-V DC supply.
9. To obtain best close-in noise (below 500-Hz offset), use a low phase noise reference signal at J11
EXT_REF_IN SMA connector.
