Introduction

The LWB5+ series wireless module is an integrated, small form factor 1x1 SISO 802.11 a/b/g/n/ac WLAN plus Bluetooth 5.0 dual mode module 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 platform-specific customization. This device is pre-calibrated and integrates the complete transmit/receive RF paths including diplexer, switches, reference crystal oscillator, and power management units (PMU). The integrated ceramic chip antenna, MHF4 RF connector, and RF trace pad are selectable from different variants. The LWB5+ series device supports IEEE 802.11ac 1x1 SISO with data rates up to MCS9 (433.3 Mbps). An internal Wi-Fi and Bluetooth coexistence scheme provides optimized connectivity while Wi-Fi and Bluetooth are working simultaneously. The device’s low power consumption radio architecture and power management unit (PMU) proprietary power save technologies allow for extended battery life. In addition, its dual 802.11ac and Bluetooth radio includes full digital MAC and baseband engines that handle all 802.11 CCK/OFDM 2.4/5 GHz and Bluetooth 5.0 (Basic Rate, Enhanced Data Rate, and Bluetooth Low Energy) baseband and protocol processing. The LWB5+ series wireless module is designed based on the Cypress CYW4373EUBGT 802.11ac/a/b/g/n chipset. It is optimized for high speed, reliability, and low-power embedded applications. It is integrated with dual-band WLAN (2.4/5 GHz) and Bluetooth 5.0. Its functionality includes the following: Improved throughput on the link due to frame aggregation, RIFS (reduced inter-frame spacing), and half guard intervals Support for LDPC (Low Density Parity Check) codes. Improved 11n performance due to features such as 11n frame aggregation (TX A-MPDU) and low-overhead hostassisted buffering (RX A-MPDU). These techniques can improve performance and efficiency of applications involving large bulk data transfers such as file transfers or high-resolution video streaming. IEEE 802.11ac, 1x1 SISO with data rate up to MCS9 (433.3 Mbps).
