Dc blocking capacitor
Dear Yeung

Didn't know how to answer to your question, therefore over this channel.
As far as I see, there is only a SAW Filter. But this Filter will block DC, doesn't it. As it is a passive antenne, there is no DC antenna supply to block.
Still needed even with this SAW filter?
Kind regards,

Hi Roger,

If there's DC ouput from the module RF_IN, then it needs a DC block at the RF trace before the connector
