Characteristic
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.
k : Linear Gain Mismatch
Amount of code change of the voltage ADC
output at the I/Q offset control
-
Amount of gain change along I and Q paths
between 1kHz to 615kHz
VCO external time constant and PLL value
Tank LC's Q value should be above 20.
Measure @100kHz away from the mid-
frequency.
Select a VCO buffer output value reduced by
-2dB. Connect output load to 50 .
