Monolithic Linear IC
LA1193M, 1193V
High-Performance FM Front End for Car Radios
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
• Double-balance mixer
• Pin diode drive output
• Differential IF amplifier
• Dual-system wide-band AGC circuit
• Local buffer output
• 3D-AGC system
• FET gate drive AGC output
• IF amplifier gain control pin
• Improved interference characteristics
— Expanded mixer input dynamic range
Mixer input usable sensitivity: 15 dBµ
Mixer input I.M. QS:
90 dBµ
(The dynamic range has been increased by 6 dB
over the earlier LA1175M.)
— Development of a new wide-band AGC circuit
Improved interference characteristics for both near-
channel interference and far-channel interference
Improved interference characteristics for the TV band
— Development of a 3D-AGC system
The adjacent channel two-signal interference
characteristics can be effectively improved without
degrading the strong-field three-signal interference
characteristics during keyed AGC operation.
• Improved temperature characteristics
— Conversion gain
— AGC sensitivity
— Antenna damping drive output current
Package Dimensions
unit: mm
unit: mm
• Improved stability design
— AGC circuit local oscillator isolation
Measures were taken to prevent the deterioration of
AMR, noise level, THD and other characteristics
during AGC operation.
— AGC circuit incorrect operation measures
The LA1193M provides methods to prevent
incorrect operation due to local oscillator injection
and loss of DC balance.

Pin No.
13 N-AGC input
LA1193M, 1193V
Equivalent circuit
Since the DC cut capacitor is provided on-chip in the
pin internal circuit, we have taken steps to prevent
incorrect AGC operation due to inter-pin leakage
14 IF AMP bypass
15 IF AMP input
18 IF AMP output
19 IF AMP gain adjust
IF gain: 25 dB
Input and output impedances of 330
The IF gain can be adjusted by inserting a resistor
between pins 17 and 19.
The gain is at its maximum when there is no resistor
16 RF AGC output
20 Keyed AGC input
Second gate control
Controls the narrow AGC.
