Maximum AGC gain. Control input signal so
that output corresponding to 3LSB is output
from ADC. The current source impedance is
500
and matched by connecting a 1k
resistance to the differential input.
Minimum AGC gain. Control input signal so
that output corresponding to 3LSB is output
from ADC. The current source impedance is
500
and matched by connecting a 1k
resistance to the differential input.
PDM is controlled to 3.3V and finds the
differential gain between the control voltage of
1V and 2V.
The difference in gain slope between when the
temperature is -30
°
C and +85
°
C.
The IF frequency is increased to find the
frequency where the gain falls below -3dB.
Input power = -102dBm
Input power = -75dBm
Input power = -25dBm
AGC gain Max.
AGC gain Min.
ADC generated harmonic frequency
component. 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 – 20MHz are
extracted and added. The AGC control
voltage is controlled so that ADC output is full
scale when the input signal is -80dBm.
In-band spurious peak value produced by IMD
based on 2 jammer signals.
One in-band signal(@50kHz,0.5*F/S)
and two jammers(@900kHz, 22dB*F/S and
@1.7MHz, 21dB*F/S)are simultaneously
input. AGC control voltage is controlled so
that ADC output is F/S when the input signal is
-80dBm.
