RF SILICON AND SUBSYSTEMS SOLUTIONS

FOR BROADBAND COMMUNICATIONS AND AUTOMOTIVE ELECTRONICS

The MT1119 is an advanced, low-

APPLICATIONS

power, highly integrated single-chip

amplifier IC specifically designed for

automotive AM/FM antenna systems

requiring low noise and very low

distortion. Additionally, the MT1119

has an integrated true-RMS power

detector and an uncommitted

systems

PRELIMINARY PRODUCT BRIEF

FEATURES

•

The MT1119 is a highly integrated and

complete RF amplifier subsystem for

active AM/FM antennas

AM input frequency range

op-amp in order to realize an AGC

function for FM by simply adding

external PIN diodes. The threshold

of the FM AGC function is variable

and can be set according to the

application requirements. The on-

chip 2.5V temperature compensated

reference generator and high output

voltage op-amp combine to form a

low-cost, reliable, automotive-

capable power supply which can be

directly derived from the car battery.

The MT1119 is capable of

0.15 MHz to 30 MHz supports

AM, DRM and HD Radio

standards in the longwave,

midwave and shortwave band

FM input frequency range

76 MHz to 162.4 MHz

supports FM and HD Radio

standards in the FM and

weather band

•

Fully integrated amplifiers for

AM and FM

Fully integrated RMS level

detector and general purpose

op-amp (PIN-diode drivers)

for easy implementation of

AGC function for FM

amplifying signals with frequencies

in the 0.15 MHz to 30 MHz range for

AM and 76 MHz to 162.4 MHz range

for FM. External components

determine the gain of the AM and

FM amplifiers and can also be

modified to extend the operating

frequency of the MT1119.

MT1119 High Performance Automotive

AM/FM Amplifier Subsystem

•

On-chip reference voltage

generator and high output

voltage op-amp builds a

reliable low-cost voltage

regulator function

The AM amplifier uses a highly

sophisticated design technology in

order to reach low noise, very low

distortion, high input impedance and

its capability to drive very low output

impedance. The FM amplifier is

matched to 50 ohms and is specially

designed to perform with very low

noise and distortion.

•

Low noise

Low power consumption

Ultra low distortion

Very high AM input

impedance

•

Very small package

Highly sophisticated

temperature compensation

design technology to support

the extended automotive

ambient temperature range

from -40° to 115°C.

The small 24-pin QFN

package of the MT1119 and the

requirement for minimal external

components enables a compact,

cost-effective solution fulfilling

automotive requirements.

•

Integrated ESD protection

Minimal external components
