Hi ,
when the SUBGHZ block is in TX mode.
if , for example , the COAX cable connected to the board SMA connector is suddenly disconnected during RF TX transmission .
what is the maximum allowed input power on the RFO_HP pin when operating in TX mode ? (due to Reflected RF power occurring from the suddenly disconnected cable)
thank you

Hello @viola
the maximum VSWR is 10:1, from this you can calculate the value you want, starting from your Pout:
If Pout = 16 dBm, max reflected power is 14.27 dBm,
if Pout = 22 dBm, max reflected power is 20.25 dBm.
