WS5121 GPS Receiver OEM Module

The WS5121 GPS Receiver OEM Module incorporates a highly sensitive 12-channel, quick time-to-fix GPS Receiver. It features the newest generation super-integrated GPS System on Chip (SoC), as well as a 15 dB gain LNA stage and a SAW filter to provide a consistent, clear signal while minimizing loss-of-lock when GPS conditions are less than ideal. The WS5121 is quickly integrated into host system with no external components needed but an external GPS antenna.

The WS5121 GPS Receiver Module is available in a very compact 27.6 mm x 25.5 mm PCB Surface Mount package, or a connectorized package.
