customers. The MT1384WFC AM/FM
Tuners combine the low system
integration effort of a standard “plug
and play” module with outstanding
features and absolute high-end
performance.
FEATURES
AM
The MT1384WFC is a high-end
AM/FM tuner module with integrated
dynamic selectivity which supports
worldwide AM and FM bands.

•
Up/down conversion
Excellent sensitivity
Superior selectivity due to highly
sophisticated filter technology
These tuner modules offer world
standard functionality by supporting
the various frequency allocations in the
US, Europe, and Asia (including
Japan). The MT1384WFC Tuner
Modules are available with either
horizontal-mount mechanics or
vertical-mount mechanics. Special
custom-designed versions are

available on request.
The AM section of the tuner module
contains an up/down conversion
system with an active prestage and an
audio output. Features such as
excellent sensitivity and very good
large signal performance, together with
the functionality of the implemented
noise blanker, help ensure that the
tuner module produces clear AM
reception - even in critical situations.
