1. Introduction
F23BUUM13-W2 is a small size and low profile of WiFi + BT Combo module with LGA (Land-Grid Array) footprint, board size is 13.2mm*12.0mm with module thickness of 2mm. 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 WiFi to connect with host processor and high speed USB interface for BT. It also has a PCM interface for audio data transmission with direct link to external audio codec via BT controller. The WiFi throughput can go up to 150Mbps in theory by using 1x1 802.11n b/g/n MIMO technology and Bluetooth can support BT2.1+EDR/BT3.0 and BT4.0.
F23BUUM13-W2 uses Realtek RTL8723BU, a highly integrated WiFi/BT single chip based on advanced COMS process. RTL8723BU integrates whole WiFi/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. The general block diagram for the module is shown in Figure 1
