MT141X AM/FM ANTENNA

AMPLIFIER SERIES

APPLICATIONS

The Microtune MT141X AM/FM

antenna amplifiers are designed for

use in automobiles with state-of-the-

art in-glass antenna systems.

Since in-glass antennas need high

performance amplifiers to supply a

clean signal to the radio, the MT141X

modules are ideal for this demanding

environment. As most in-glass

• Car radio applications

• Automotive in-glass-antenna

systems with or without

diversity

PRODUCT BRIEF

The MT141X modules are optimized to

work with in-glass antennas. The

amplifiers are customized to meet the

specific housing, connector and

electrical matching requirements of

varied car platforms that deploy

different antennas, radios, and

mechanics.

AM FEATURES

• World standard frequency

range: 150 kHz to 6290 kHz

• Very high input impedance

• Very low input capacitance

• Low output impedance

• Low IM2 distortion

antennas employ multiple FM

antennas, but use only one AM

antenna to add a diversity function for

FM, the MT141X amplifiers are

available in an AM/FM version and an

FM-only version.

• Input protection

They are engineered to deliver high

linearity and low noise, critical

FM FEATURES

• World standard frequency

range: 76 MHz to 108 MHz

• Integrated AGC circuit

• Low IM3 distortion

• Low noise figure

• Input protection

• Suitable for antenna diversity

applications

features of an automotive AM/FM

receiving system. A low noise figure

enables high system sensitivity to

receive clear sound in rural areas,

while high linearity permits robust

performance in dense, urban signal

environments. The implemented AGC

circuit for FM provides additional

improvement of signal handling

capability.

GENERAL FEATURES

MT141X AM/FM Antenna Amplifier Module

The MT141X amplifiers also permit

designers to adjust key parameters,

including gain, AGC threshold, or

input/output impedance, providing the

flexibility to optimize performance and

integration of entire AM/FM receiver

system. Features such as phantom

power supply (power is supplied from

the car radio via the antenna cable)

are additionally offered as an option.

The power supply circuit includes

reverse voltage protection and the

antenna input provides ESD

• High performance voltage

stabilizer on board

• Reverse voltage protection

• Low power consumption

• High stability over temperature

• Optional phantom power

supply

• Customizable key parameters,

frequency range, housing, and

connectors

• Compact customized size of

around 13 cm²

• Meets automotive quality

standards

protection. The amplifiers support the

frequency ranges of Japan, Europe

and the United States.
