High-Performance FM Front End for Car Radios
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
— Expanded mixer input dynamic range
Mixer input usable sensitivity: 15 dBμ
Mixer input I.M. QS:
(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.
90 dBμ
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.
Improved temperature characteristics
— Conversion gain
— AGC sensitivity
— Antenna damping drive output current
