CM-8733BS is a small size and low profile of WiFi+BT combo module with LGA(Land-Grid Array) footprint, board size is 12mm*20mm with module height of 2.0 mm. It can be easily manufactured on SMT process and highly suitable for tablet PC, ultra book, and mobile device and consumer products.It provides SDIO interface for WiFi to connect with host processor and high speed UART 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 provides higher data rates of 54Mbps and 150Mbps for 802.11g and 802.11n OFDM respectively and Bluetooth can support BT2.1+EDR/BT5.2

CM-8733BS uses Realtek RTL8733BS, a highly integrated WiFi/BT single chip based on advanced COMS process. RTL8733BS integrates whole WiFi/BT function blocks into a chip, such as SDIO/UART, MAC, BB, AFE, RFE, PA, EEPROM and LDO/SWR,except fewer passive components remained on PCB.
