原创 汉微芯（代理西南） GPS卫星接收模块XN934/体积最小

Swid-XN934

Low Cost Very High Performance

SMD GPS Module

The Swid-XN934 is a small form factor GPS module solution intended for a broad range of Original Equipment Manufacturer (OEM) products, where fast and easy system integration and minimal development risk is required.

The Swid-XN934 GPS receiver’s -159dBm tracking sensitivity allows continuous position coverage in nearly all application environments. Its high performance search engine is capable of testing 4,000,000 time-frequency hypotheses per second, offering industry-leading signal acquisition and TTFF speed.

The receiver is optimized for applications requiring high performance, low power, and low cost; suitable for a wide range of OEM configurations including mobile phone, PND, asset tracking, and vehicle navigation products.

The very small 13mm x 16mm form factor and the SMT pads allow standard surface mount device pick-and-place process in fully automated assembly process; enabling high-volume, very cost-efficient production.
