Introduction

The MSD50NBT module (which uses an SDIO interface) is a 2x2 MIMO 802.11 a/b/g/n WLAN plus Bluetooth 4.0 dual mode device that is optimized for low-power mobile devices. The integration of all WLAN and Bluetooth functionality in a single package supports low cost and simple implementation along with flexibility for platformspecific customization. This device is pre-calibrated and integrates the complete transmit/receive RF paths including baluns, mobile phone coexistence band pass filter, diplexer, switches, power amplifier, low noise amplifier, and reference crystal oscillator. The MSD50NBT device supports Bluetooth 2.1+EDR and Bluetooth 4.0 (Bluetooth Low Energy or BLE). The device’s low power consumption radio architecture and proprietary power save technologies allow for extended battery life. When operating on channels in the UNII-2 and UNII-2 Extended bands that are in the 5GHz portion of the frequency spectrum and are subject to Dynamic Frequency Selection requirements, the MSD50NBT fully conforms to applicable regulatory requirements. In the event that specified types of radar are detected by the network infrastructure, the MSD50NBT fully conforms to commands from the infrastructure for radar avoidance. The MSD50NBT interfaces to host devices via a 60-pin connector (Molex 60-pin connector). The I/O voltage level configuration (either 3.3 V or 1.8 V) is required from the host platform to configure the SDIO bus signal to run at a 3.3 V or 1.8 V signal level. In addition, its dual 802.11 and Bluetooth radio includes full digital MAC and baseband engines that handle all 802.11 CCK/OFDM 2.4/5GHz, and Bluetooth basic rate and EDR baseband and protocol processing. MSD50NBT has its own RF shielding and does not require shielding provided by the host device into which it is installed in order to maintain compliance with applicable regulatory standards. As such, the device may be tested in a standalone configuration via an extender card.
