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.
Functions
• 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
Features
• Improved interference characteristics
• Improved stability design
— Expanded mixer input dynamic range
— Development of a new wide-band AGC circuit
— Development of a 3D-AGC system
— AGC circuit local oscillator isolation
— AGC circuit incorrect operation measures
Mixer input usable sensitivity: 15 dBµ
Mixer input I.M. QS:
(The dynamic range has been increased by 6 dB
over the earlier LA1175M.)
Improved interference characteristics for both near-
channel interference and far-channel interference
Improved interference characteristics for the TV band
The adjacent channel two-signal interference
characteristics can be effectively improved without
degrading the strong-field three-signal interference
characteristics during keyed AGC operation.
Measures were taken to prevent the deterioration of
AMR, noise level, THD and other characteristics
during AGC operation.
The LA1193M provides methods to prevent
incorrect operation due to local oscillator injection
and loss of DC balance.

... 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 500 Ω ...
