Overview
The LA1193M and LA1193V are front-end ICs developed for use in car radios. It incorporates an extremely wide dynamic
range mixer and a new AGC system consisting of a dual-system wide-band AGC and a new keyed AGC to provide
excellent interference suppression characteristics.
Features

1. Oscillator Circuit
Steps were taken to prevent AMR degradation during earlier product type
AGC operation, since the local oscillator block in this IC has independent
Vd (pin 5) and ground (pin 3) connections.
This is a Colpitts oscillator and has the same structure as that used in
earlier circuits. The oscillation level and intensity are changed by
capacitors C2-4, C4 and CP.
2. Local Oscillator Buffer Output
This buffer is an emitter follower circuit.
If desired, the buffer efficiency can be increased by inserting a resistor
between pin 1 and ground to pass more current through the buffer
transistor. However, this current must be limited so that Pdmax for the
package is not exceeded.

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.
No.4715-9/22
LA1193M, 1193V
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.

• 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.

3D-AGC Sensitivity, ∆f and V20 Characteristics
— The W-AGC sensitivity is determined by the antenna RF circuit selectivity independently of V20.
— The N-AGC sensitivity is determined by the antenna, RF and mixer circuit total selectivity when V20 is 0.6V or
greater. It is determined by that selectivity and V20 when V20 is over 0.6V.
— The improvement in two-signal sensitivity suppression is the shaded area in the total AGC sensitivity and
corresponds to the section occupied by the N-AGC.

(Improved by 6.0dBµ over previous products.)
IMQS is the interference 1 and 2 input levels such that when an
interference signal with the same level is input to the mixer and
distortion occurs at the mixer, the generated IM output has a S/N

Temperature Characteristics
The LA1193M/V uses Vref temperature characteristics correction to hold the gain temperature characteristics to the
low level of about 1dB over the range −30 to +80°C.
6. AGC Circuit
The LA1193M/V uses pin diode antenna damping (pin 9) and MOSFET second gate voltage control (pin 16) for AGC.
The AGC operating sequence is as follows :
Antenna damping (pin diode) → MOSFET second gate voltage control
(attenuation) 20dB
(attenuation) dB
The above AGC sequence is used for the following reasons.
• Intermodulation distortion can occur if a signal of 110dBµ or larger is input to the antenna circuit varactor diode.
In such situations, if the AGC sequence was MOSFET second gate voltage control followed by pin diode antenna
damping, as long as the receiver was not in a strong field where the 60dB or higher AGC attenuation operates, input
limitation due to the antenna circuit varactor diode would operate. Therefore, we feel that the AGC operating
sequence employed is appropriate.
• Consider the problem of AGC loop stability. If the two AGC loops (the antenna damping AGC loop and the MOSFET
second gate control AGC loop) operate, the AGC system would become unstable and have an excessively large
influence on the transient response. Therefore the following structure cannot be used.
MOSFET second gate control → antenna damping → MOSFET second gate control
The AGC operating conditions are the same as those for the LA1175M.
• Narrow AGC circuit
Since the LA1193M/V’s N-AGC (which detects the mixer output) is set to have a high sensitivity, care is required to
avoid incorrect operation. In particular, there must be adequate separation from the local oscillator block on the
printed circuit board pattern. Also, a resistor of at least 500Ω must be inserted at the pin 13 input. A low-pass filter is
formed by the insertion of this resistor. This low-pass filter prevents incorrect AGC operation due to the local
oscillator.
• The AGC sensitivity setting can be changed by adjusting the
value of the capacitor connected at pin 13. Although the AGC
sensitivity can be lowered by increasing the value of the series
resistor, caution is required since the AGC has its own frequency
characteristics.
No.4715-12/22
LA1193M, 1193V
• Wide AGC circuit
The wide AGC sensitivity is set by the value of the capacitor on pin 8. However, since incorrect operation due to the
local oscillator signal may occur if this capacitor is too large, its value must be chosen carefully.
• 3D-AGC
If the difference in sensitivity between the N-AGC and the W-AGC systems is too large during 3D-AGC operation,
the S/N ratio can be degraded in the vicinity of the input where the AGC switches. Therefore, the 3D-AGC setting
values must be selected carefully. Although this problem can be ameliorated by applying a time constant to pin 20, in
principle, this S/N ratio degradation should be prevented by limiting the sensitivity difference between the two AGC
systems.
