6.12.16.7 RX intermodulation
RX intermodulation. Desired signal level at PIN = -64 dBm. Two interferers with equal input power are
used. The interferer closest in frequency is not modulated, the other interferer is modulated equal with
the desired signal. The input power of the interferers where the sensitivity equals BER = 0.1% is presented.
