3D AGC Sensitivity — ? f, V 23 characteristics
? The wide AGC sensitivity is determined by the antenna and RF circuit selectivity, regardless of V 23 .
? The narrow AGC sensitivity is determined by the following.
The total selectivity of the antenna, RF circuit, and mixer when V 23 ≥ 0.5 V
The above selectivity and V 23 when V 23 < 0.5 V
? The improvement in the second-channel attenuation corresponds to the area occupied by the narrow AGC in the
total AGC sensitivity area.
Figure 8 on the next page shows the actual operation of the circuit.
