LW123M-P
GPS Antenna Module
Introduction
LW123M-P is a highly integrated GPS RF Antenna Module designed for GPS application with low power and low cost. The device consists of SiRFstarIV GPS chip and Lexiwave’s highly efficient antenna for best GPS reception sensitivity and antenna pattern.
Its integrated SAW 2.4GHz notch filter coupled with DSP based jammer removal gives superior interference rejection on, Cellular phone, Bluetooth and WiFi signals. It is particularly suitable for smart phone, tablet PC applications in which multiple RF signals may co-exist.
LW123M-P operates on a 3V positive power supply with 1.8V CMOS compatible UART 9600bps host processor interface. The module can enter a micro-power mode while maintaining Hot Start TTFF condition while consuming only 50µA.
