Features of the Double Wide AGC System
— Since this is a mixer input detection wide-band AGC, it prevents the occurrence of intermodulation due to
interfering stations with
∆f > 1MHz. (TV band interference prevention)
— Since this system uses a narrow AGC at the same time, the wide AGC sensitivity can be lowered, thus preventing
incorrect operation due to local oscillator injection.
— Optimal sensitivities for any field conditions can be set, since the sensitivities of both the wide and narrow AGC
systems can be set by changing the values of external components.
— The input level of the desired station is limited by the narrow AGC. As a result, excessive levels are no longer input
to the stages that follow the mixer and the beats at multiples of 10.7
× A are reduced.
• Two-Signal Sensitivity Suppression Characteristics
Previously, keyed AGC systems were used to provide good intermodulation distortion and two signal sensitivity
suppression characteristics at the same time. However, in previous keyed AGC systems, when the desired station
would fade or drop out, the wide band AGC level would become essentially zero. As a result, the automatic station
selection function would malfunction and blocking oscillation would occur in the presence of strong interfering
stations. Thus keyed AGC systems were extremely hard to use in actual practice. Sanyo has developed a new AGC
system (3D-AGC) that solves these problems and allows the construction of extremely simple application circuits.
The LA1193M/V incorporates this AGC system.
What is the 3D-AGC system?
It is a system that determines the wide-band AGC level by using information that has the following three frequency
characteristics.
RF and antenna circuit information
Mixer input AGC
Mixer circuit information
Mixer output AGC
C, F and selectivity information
S-meter output
3D-AGC Features
Feature
Merit
The narrow AGC sensitivity, which operates for
∆f of less than 1.5MHz, is
controlled independently according to the field strength of the desired
station.
• This is effective as a measure for mitigating two signal sensitivity
suppression.
The narrow AGC sensitivity is controlled at V20 values under 2V.
• This allows two signal sensitivity suppression to be mitigated without
deterioration in the three signal characteristics.
The wide AGC operates even when V20 is zero, i.e., when the desired
station does not exist.
• This allows the prevention of incorrect stopping on intermodulation
signals during search.
• This allows the prevention of intermodulation occurring in the
antenna and RF modulation circuits in the presence of strong
interfering stations. Prevention of blocking oscillation due to AGC
operation is also possible.
The N-AGC and the W-AGC sensitivities can be set independently.
• This allows optimal settings to match the reception field conditions.
The system has two AGC systems, the N-AGC and the W-AGC.
• Since the narrow AGC operates at the desired station and at
adjacent stations, it is possible to reduce the wide AGC sensitivity.
This prevents incorrect AGC operation due to local oscillator
injection.
