The Sona IF and Sterling LWBx family consists of five different radios, with varying form factors and interfaces.

Sona IF573

The Sona IF573 is a tri-band a/b/g/n/ac/ax Wi-Fi 6E + BT 5.4 2x2 MIMO radio based on the Cypress CYW55573 chipset. It is offered as a solder down M.2 1318 module with MHF4 antenna connectors or trace pins as well as a pluggable 2230 M.2 E-Key module with MHF4 antenna connectors. The Sona IF573 supports either PCIe or SDIO host interface for Wi-Fi and a UART interface for Bluetooth. A development kit is available with all interfaces brought to convenient headers.

Note: The Sona IF573 M.2 module comes in two variants that differ in supported host interface based on how the integrated Sona IF573 module is populated. Be sure to correctly identify which M.2 variant you have (SDIO/UART or PCIe/UART) as integration requirements are different.

Sterling LWB+

The Sterling LWB+ is a 2.4GHz b/g/n Wi-Fi + BT 5.2 SISO radio based on the Cypress CYW43439 chipset. It is offered as a solder down module with integrated chip antenna or antenna connector, a pluggable 2230 M.2 E-Key module with MHF4 antenna connector, and as a SIP without the front-end antenna circuitry. The Sterling LWB+ supports an SDIO 2.0 host interface for Wi-Fi and a UART interface for Bluetooth. A development kit is available consisting of the LWB+ module mounted to a carrier board with a full size SDIO interface, and all available interfaces brought to convenient headers.

Sterling LWB5+

The Sterling LWB5+ is a dual band a/b/g/n/ac Wi-Fi + BT 5.0 SISO radio based on the Cypress CYW4373E chipset. It is offered as a solder down module with integrated chip antenna or antenna connector, an M.2 module with integrated antenna connectors supporting antenna diversity, and as a pluggable USB adapter. The Sterling LWB5+ supports an SDIO 3.0 host interface for Wi-Fi and a UART interface for Bluetooth, or a shared USB host interface that supports both Wi-Fi and Bluetooth. Multiple development kits are available for the LWB5+ including a module based kit that supports all host interfaces and power supply configurations, as well as an M.2 development kit supporting either the SDIO/UART or USB/USB M.2 variants.

Note: The LWB5+ M.2 module comes in two variants that differ in supported host interface based on how the integrated LWB5+ module is populated. Be sure to correctly identify which M.2 variant you have (SDIO/UART or USB/USB) as integration requirements are different.

Sterling LWB

The Sterling LWB is a 2.4GHz b/g/n Wi-Fi + BT 4.2 SISO radio based on the Cypress 4343W chipset. It is offered as a solder down module with integrated chip antenna or antenna connector, as well as a SIP without the front-end antenna circuitry. The Sterling LWB supports an SDIO 2.0 host interface for Wi-Fi and a UART interface for Bluetooth. A development kit is available consisting of the LWB module mounted to a carrier board with a full size SDIO interface, and all available interfaces brought to convenient headers.

Sterling LWB5

The Sterling LWB5 is a dual band a/b/g/n/ac Wi-Fi + BT 4.2 SISO radio based on the Cypress CYW43353 chipset. It is offered as a solder down module with integrated chip antenna or antenna connector, as well as a SIP without the front-end antenna circuitry. The Sterling LWB5 supports an SDIO 3.0 host interface for Wi-Fi and a UART interface for Bluetooth. A development kit is available consisting of the LWB5 module mounted to a carrier board with a full size SDIO interface, and all available interfaces brought to convenient headers.
