Details Information


6223E-UUD is a small size and low profile of Wi-Fi + BT Combo module, board size is 12.2mm*13mm. It can be easily manufactured on SMT process and highly suitable for tablet PC, ultra book, mobile device and consumer products. It provides USB interface for Wi-Fi and Bluetooth. The module provides simple legacy and 20MHz/40MHz co-existence mechanisms to ensure backward and network compatibility and Bluetooth can support BT2.1+EDR/BT3.0 and BT4.2. 

6223E-UUD uses highly integrated Wi-Fi/BT single chip based on advanced COMS process. 

6223E-UUD integrates whole Wi-Fi/BT function blocks into a chip, such as USB, MAC, BB, AFE, RFE, PA, EEPROM and LDO/SWR, except fewer passive components remained on PCB. 

This compact module is a total solution for a combination of Wi-Fi + BT technologies. 

The module is specifically developed for Smart phones and Portable devices.
