Description
LP-GPX-05-NFF
The LP-GPX-05-NFF high performance series is an exceptional DC pass design for protection of GPS receivers requiring up to 5Vdc power to be supplied on the centre pin. While the RF path is DC blocked, the biased DC voltage protection circuit uses Solid State protection technology to provide unsurpassed surge performance.
The LP-GPX-05 series offers outstanding Insertion Loss and Return Loss characteristics over the 1000-2000MHz band, making it suitable for protection of commercial and military GPS, as well as other applications in this band.
Unlike competitive protectors, the white bronze plated construction of the LP-GPX-05-NFF series eliminates potential galvanic corrosion issues and provides long life in hostile environments. The fully weatherized housing is sealed to IP65 allowing for outdoor as well as indoor installation.
The LP-GPX-05-NFF is a direct, drop in replacement for Polyphaser DGXZ+06-NFNF-A and DGXZ+06-NFNF-B
LP-GPX-05-NFF Series:
- LP-GPX-05-NFF N Female connectors on surge and protected sides – bidirectional
- LP-GPX-05-NFM N Male connector on one side & N Female connector on the other side bidirectional
