POWER-SUPPLY RECOMMENDATIONS
Figure 278. Merged LO Supplies
Note: is a schematic notation to merge nets with different names. There is no real component here. The rest of the power supplies need
their own FB/cap filter network.
Implementing and testing this power solution shows no visible signs of RF performance degradation in phase noise or additional spurs, or any
other system level issues. Any noise on the power supplies inadvertently affects the RF output of the part. So, be cautious when designing a
power solution.

SUMMARY

The design specification for the ADRV9001 EVB shows the best performance of the part with little to no degradation from the PCB design. The
Analog Devices applications engineering team recommends the circuit board layout and power-supply decoupling covered in this document.
These recommendations are based on circuit analysis, simulation, best practice layout techniques, and experience with this and other
transceiver devices. Designers are strongly encouraged to follow these guidelines carefully when developing their own PCB applications.
Deviation from these recommendations are possible (but may result in substandard system performance that is very difficult to isolate after the
system is committed to a PCB design). The ADRV9001 demo board layout files and schematics use many of the recommended techniques.
