312 Series GPS LNAs Pre-Filtered GPS LNA (Low Noise Amplifier) Designed to amplify GPS signals while protecting the GPS receiver by filtering out interferers Applications Features • Pre-Filtered • Inline Booster • Low Noise Figure, 1.8 dB Typical • Satellite Navigation • Wide Input Voltage Range • Avionics • Tested to many MIL-STD-810 & MILSTD-461 Requirements • Marine Navigation • Small Lightweight Hermetic Package • Military • Survey/Mapping • Contact factory for custom configurations 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 API Technologies’ 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.
