SAW filter for nRF21540

[Invicton_Matt]

Hello,

We are working on a project based on the Thingy91x which uses the following SAW filter : SAFFB2G45MA0F0A. Unfortunately this part seems to be out of stock everywhere I looked? I found these two parts that seem to be suitable replacement : B39242B8852P810 or ABSES4AL-45CM03AM.

Would it be possible for you to help me find the best alternative? Either of the two component above or something else?

Thank you

M.

Hi,

Thanks for contacting us. I just checked the specs of the proposed SAW filters and seems both of them are good candidate as an alternative to SAFFB2G45MA0F0A. Just please pay close attention to matching recommendations in datasheet when using new SAW filter.

Best regards,
Ressa

Hello Ressa,

I am not too sure what you mean by "matching recommendations" which datasheet are you referring too here? The SAW filter or the the Thingy91X?
