Introduction

General Description

The Sona TI351 series wireless module is an integrated, small form factor Wi-Fi/Bluetooth module that is optimized for low-power mobile devices, featuring:

  • Wi-Fi 6:  Dual-band 1x1 IEEE 802.11a/b/g/n/ax WLAN
  • Bluetooth® 5.4:  BLE

The integration of all WLAN and Bluetooth functionality in a single package supports a low cost and simple implementation along with flexibility for platform-specific customization.  The radio is pre-calibrated and integrates the complete transmit/receive RF paths including bandpass filter, diplexer, switches, reference crystal oscillator, and power management units (PMU).  It is available in both M.2 2230 E-Key and M.2 1216 solder-down form factors with an MHF4 antenna connector.  The M.2 1216 module is also available with an integrated chip antenna variant.  For a list of certified antennas see Table 31 in this datasheet.

The Sona TI351 series device supports IEEE 802.11ax dual-band (2.4/5 GHz) single streams with data rates up to MCS7 (86 Mbps PHY data rate for 2.4/5 GHz).  The fully integrated Wi-Fi and Bluetooth radios includes full digital MAC and baseband engines that handle all 802.11 CCK/OFDM/OFDMA® 2.4/5 GHz and Bluetooth Low Energy 5.4 baseband and protocol processing.

Ordering information is listed in Table 1.  Please contact Ezurio Sales/FAE for further information.
