LA1193M, 1193V

No.4715-9/22

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.
