Really appreciate your reply. The carrier frequency that I use is 6MHz. I
would like to try the preamplifier that you recommended.
I got another problem which may clear the reason why I met this problem. I used
a signal generator to produce a 6.01MHz sinusoid wave. After down conversion by
6MH

Dear all,
I'm using LFRX to detect a -120dBm signal. According to my measurement, the
lowest power of signal that LFRX is able to detect is -90dBm. I tried deploy a
preamplifier to amplify the received signal by certain dB in order to reach the
-90dBm, but this turned out that noise is amplifie
