88W8997. FCC certification. Intermodulation test.

Hello,

We designed a custom LTE router board with 1YM Murata onboard (based on 88W8997 ).

Now we are trying to conduct an Intermodulation test. Thus, we want to see the behavior of the board while LTE and WiFi transmit simultaneously.

But, in case we test LTE BAND 30 or Band 41 + WiFi we always come across a problem. In such a case WiFi transmission suddenly stops.

Could you tell us where to look for the problem?

Where to find possible clues for a solution?

Hello @Oleg_G ,

Thank you in advance for contacting NXP support. In this case ca you please help me with the following question in order to proportionate the proper solution.

Does the WiFi transmission works properly before the coexistence?
Did you follow any Application Note for this LTE WiFi configuration?
