3. Interference Characteristics
The LA1193M incorporates a newly developed 3D-AGC (triple dimension) circuit. This circuit allows three-signal
interference characteristics (inter-modulation characteristics) and two-signal sensitivity suppression characteristics to
be provided at the same time, a combination of characteristics previously thought difficult to achieve.
• Inter-Modulation Characteristics
The LA1193M prevents inter-modulation distortion by applying two wide-band AGC circuits.
This double wide-band AGC system consists of two AGC circuits and a narrow AGC (pin 13 input, mixer input
detection type) as shown in Figure 1. Figure 2 shows the antenna input frequency characteristics.
