Dear Sir,

regarding to M20072 antenna tuning, please refer to datasheet chapter10.2 External matching.
when doing the antenna tuning, please remove the C22 first and solder RF cable feeding at C22 pad close to M20072 pin4 ANT_OUT, and then adjust L1 and C1 to the optimized S11 curve.

Regards

Raymond
