WL1831MOD: WL1831MOD RF_ANT2

Part Number: WL1831MOD
Other Parts Discussed in Thread: WL1835MOD

Hello TI Expert,

 

I have got a question from our customer about the WL1831MOD RF_ANT2.

 

Our customer has designed their own board by referring to the WL1835MOD reference schematics.

If they use WL1831MOD, is it good that RF_ANT2 is not connected? Or, any pullup or pulldown is needed?

Please let me confirm whether RF_ANT2 can be Not Connected.

 

In this case, if there is only RF_ANT1 pattern of WL1835MOD on their custom board, can they get a certification from FCC/TELEC?

 

Thank you for your advice.

 

Best Regards,

Nobu Arai
