CM-6620B is a 4-in-1 Module which includes WLAN, Bluetooth, GPS and FM transmitter/receiver. With four advanced radio technologies integrated into a module, it provides the best and most convenient connectivity functions.

CM-6620B implements advanced and sophisticated radio coexistence algorithms and hardware mechanisms. It supports dual antennas that 2.4GHz antenna is for Wi-Fi & Bluetooth and 1.575GHz antenna is for GPS. Enhanced overall quality for simultaneous voice, data and audio/video transmission on mobile devices can be achieved.

The small size with low power consumption reduces PCB layout area. It is designed to provide excellent performance, reliable, cost-effective and low power consumption module solution for all Tablet PC devices and mobile Internet devices. CM-6620B provides two methods for RF antenna. One is via iPex RF connector. Another method is to use RF pinout in the module.
