PCTEL 3915D-HR High Rejection Low Power GPS Antenna

PCTEL 3915D-HR High Rejection Low Power GPS Antenna

The PCTEL 3915D-HR high rejection GPS antenna offers a very lowest power consumption and impressive out-of-band filter performance making it an ideal solution for power-critical GPS applications.



The PCTEL 3915D-HR high rejection GPS antenna has one of the industry’s lowest power consumption and best out-of-band filter performance. It features ESD circuit protection, an innovative very low power two-stage low noise amplifier and dual high rejection SAW filters. The 3915D-HR also features a custom designed ceramic patch element that minimizes detuning effects caused by adjacent objects.

The 3915D-HR antenna provides consistent, clear GPS signal reception while minimizing loss-of-lock in high-RF fields. Housed in a weatherproof magnetic or screw mount enclosure, the 3915D-HR is ideal for most demanding, power critical GPS applications.
