LM843 Series

Note : Your request will be directed to LM Technologies.

The LM843 Series from LM Technologies are 2.4/5 GHz WiFi and Bluetooth 5.0 Combo Modules. This dual combination SMT module off­ers a wide range of solutions and can support 2-streams (802.11 a/b/g/n/ac) with Multi-user MIMO connections while operating under enhanced power management. They can provide theoretical data rates of up to 866.7 Mbps (Wi-Fi) and 2 Mbps (Bluetooth). These modules have a receiver sensitivity of -76 dBm (Wi-Fi) and -85 dBm (Bluetooth) and deliver up to 17 dBm (Wi-Fi) and 8 dBm (Bluetooth) of output power. The CE / FCC certified and RoHS, REACH and WEEE compliant modules are based on a Realtek chipset and require a 3.3V for operation. These modules are compatible with Linux, Windows (7 & 8), and support the Host Controller Interface (HCI) and USB (2.0) interface that has a maximum throughput of 480 Mbps. They are available inside an onboard metallic frame and measures 25 x 12 x 2 mm. The modules have 2 IPEX connectors or 2 RF lines for Antenna connections.
