The new Synaptics SYN43711 SoC integrates Wi-Fi 6/6E and Bluetooth 5.3 radios on a single state-of-the-art system on chip (SoC) to reduce the space, cost, power, complexity, and time to market of wirelessly enabled connected devices. The Wi-Fi radio is IEEE 802.11ax compliant with legacy support for 802.11a/b/g/n/ac and has a 1 x 1 antenna arrangement for a throughput of up to 600 Mbps. The Bluetooth 5.3 radio features LE Audio for multiple concurrent Bluetooth audio streaming connections.
The SYN43711 explicitly targets use cases that demand superior Wi-Fi throughput and range with seamless network interoperability. "The SYN43711 is a high-performance Wi-Fi and Bluetooth solution that enables a broader range of network edge applications. These include video distribution, where consistently high throughput is required, and AI-enabled compute, where data must be communicated securely and reliably with low latency," says Brandon Bae, Senior Director of Product Marketing at Synaptics.
The SYN43711 is a single-stream (1x1, 600 Mbps) device that complements Synaptics’ dual-stream (2x2, 1200 Mbps) SYN43756E and Triple Combo (SYN438x series). The SYN43711 gives manufacturers a more cost-effective, small-form-factor option for high-performance consumer, industrial and enterprise applications.
Innovations include support for Wi-Fi Sensing, using a proprietary algorithm to analyze Channel State Information (CSI). The algorithm allows any Wi-Fi-connected embedded device to detect the presence of humans, estimate their motion, approximate their location, and sense subtle gestures and movements, like breathing.

The SYN43711 is available in the two most widely used WLBGA packages: standard and plated-through-hole (PTH) compatible. PTH lowers PCB implementation costs. Synaptics is now sampling the SYN43711 to key customers, with production quantities available in Q1, 2024.
