what is the RX p1dB in rx gain index 0, i can see IIP3 range 20 to 76 and translate to P1dB curve, but still exclude range 0 to 19;
i experiment rx gain index 0, when i input a Fo+500K@0dBm single tone, the harmonic spur is great according to FFT below; but the 0x2b8 peak detector register read back value is 0x00 which indicated null is overload!
if i reduce the power to -10dBm, the harmonic will decrease obviously.
so it mean that the P1dB in rx gain index 0 is about -10dBm? it seem strange.
