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:

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 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
