WS3954/WS3964: Perfectly suited for OEM applications

The WS3954/WS3964 GPS antennas are ideal for personal GPS applications including handheld computers and PDAs. With an industry leading 2mA current, and compact size, the WS3954/WS3964 series is perfectly suited for OEM applications. And performance is not sacrificed; the antenna'still features a custom designed ceramic patch element along with a low noise amplifier and SAW filter, enabling the WS3954/WS3964 to provide a consistent, clear signal while minimizing loss-of-lock. Chose the WS3964 with an internal ground plane or the WS3954 without to suit your application.

Designed for low power use while maintaining GPS performance, the WS3954/WS3964 antenna's advanced circuitry integrates a SAW filter and low-noise amplifier to ensure a reliable and clear signal for the GPS receiver even in difficult conditions. The antenna design and industry leading low current draw makes the WS3954/WS3964 antenna ideal for portable or telematics applications using MONITOR, STANDBY or SLEEP modes.
