6. The TRF3722 phase noise at 1800-MHz frequency at the LO_OUTP SMA connector is shown in
Figure
15.
7. Obtain optimum phase noise performance by using linear clean power supplies at TP3 3.3-V DC
supply and TP4 5-V DC supply.
8. Obtain best close-in noise (below 500-Hz offset) by using a low phase noise reference signal at the
J11 EXT_REF_IN SMA connector. When operating the board using an external reference, make sure
to DNI R23, remove JP4, and populate R25.
