component. ADC generated Two signals in
the in-band are each mixed with signals which
will allow ADC to produce -7dB output signals.
The harmonic and non-harmonic components
of the ADC output signals between 1kHz to
20MHz are extracted and added. The AGC
control voltage is controlled so that ADC
output is full scale when the input signal is -
80dBm.
Spurious content In-band spurious peak value produced by IMD Jspur
-
related to jammer based on 2 jammer signals.
One in-band signal(@1kHz,0.5*F/S)
and two jammers(@60kHz, 22dB*F/S and
@122kHz, 4dB*F/S)are simultaneously input.
AGC control voltage is controlled so that ADC
output is F/S when the input signal is -80dBm.

-
jammer desense The in-band signal at -93dBm (control the
AGC control voltage to 0.5*F/S)and the
jammer signal at 900kHz and -53dBm are
simultaneously input. The gain reduces if the
input/output range is small in BBA.

to FM
