SIM39EA数据手册RF/IF射频/中频RFID的射频收发器模块调制解调器规格书PDF

描述 Description

SIMCom presents a high performance GPS antenna module - SIM39EA. This is a standalone L1 frequency GPS module include an embedded patch antenna on it. Designed with MTK’s high sensitivity navigation engine, it allows you to achieves the industry’s highest levels of sensitivity, accuracy, and Time-to-First-Fix (TTFF) with lowest power consumption. And with embedded antenna in SMT type, it is very easy to do customer application.
