Wi-Sys WS3955 / WS3965

The WS3955 / WS3965 embedded GPS antenna series has the industry's lowest current figure.


The WS3955 / WS3965 series is ideal for personal GPS applications including Handsets, Ultra Mobile PC’s, and PDAs. This series feautures a perfectly tuned custom ceramic patch element that minimizes detuning effects caused by adjacent pbjects. As well it features ESD circuit protection, the industry leading 1.3 mA low noise amplifier and a high rejection SAW filter which enable these antennas to provide a consistent, clear signal while minimizing loss-of-lock even when GPS conditions are less than ideal. The WS3955 comes in a compact square package and the WS3965 comes with a 45.2mm diameter mini ground-plane.
