The 312 series pre-filtered GPS LNA module is designed
to amplify GPS signals while protecting the front end of
the GPS receiver by filtering out interferers from an
increasingly crowded EM spectrum. The module
leverages Spectrum Microwave's core competencies in
low-loss filter, amplifier and mechanical design that
results in a module that maximizes out of band
rejection while minimizing system noise figure and
maintaining a small size. The pre-filtered GPS LNA is
offered in a wide range of performance options
including GPS band configuration, gain level, supply
voltage, multiple outputs and input and output
connectors.
