pcb design of ADF4355

Hello there!

Unfortunately, there are no available libraries for this part: ADF4355BCPZ-RL7. However, you can request it by going to the part page here and click "Request Now": https://www.snapeda.com/parts/ADF4355BCPZ-RL7/Analog%20Devices%20Inc./view-part/

I tried looking for a similar part and found out that this part: ADF4351BCPZ, has the same footprint dimensions with ADF4355BCPZ-RL7, However, the only difference with the footprint is the exposed pad size. In terms of symbol, you might want to use the symbol for ADF4351BCPZ and edit the pin mapping. You can download the Altium library for ADF4351BCPZ here: https://www.snapeda.com/parts/ADF4351BCPZ/Analog%20Devices%20Inc./view-part/

Let me know if you have any other questions or need any further assistance.
