MT141X AM/FM ANTENNA
AMPLIFIER SERIES
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.
MT141X AM/FM Antenna Amplifier Module
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
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.
They are engineered to deliver high
linearity and low noise, critical
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.
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
protection. The amplifiers support the
frequency ranges of Japan, Europe
and the United States.
