Overall gain reduction due to one jammer.
The in-band signal at -97dBm (control the
AGC control voltage to 0.5*F/S)and the
jammer signal at 900kHz and -57dBm are
simultaneously input. The gain reduces if the
input/output range is small in the BBA.
AGC gain. The input signal level showing 1dB
difference from its idealistic linear line when
the output signal increase, which results from
the input exceeding the output and input
range, starts to saturate.

Maximum AGC gain. Control input signal so
that ADC outputs 0.5*F/S. The current source
impedance is 500
and matched by
connecting a 1.2k
resistance to the
differential input.
Minimum AGC gain. Control input signal so
that ADC outputs 0.5*F/S. The current source
impedance is 500
and matched by
connecting a 1.2k
resistance to the
differential input.
PDM is controlled to 3.3V and finds the
differential gain between the control voltage of
1V and 2V.
