Since Skyworks acquired smart interface innovator Avnera Corporation in August 2018, the company is now able to complement its own range of wireless connectivity modules with Avnera's own ultra-low power analog circuits that are enabling smart interfaces. With the acquisition, Skyworks is also able to offer a complete range of custom Analog System-on-Chip (ASoC) solutions for audio, voice, speech, sensor and artificial intelligence (AI) applications.
“High-fidelity audio systems are elevating today’s smart home beyond mere conveniences to premium entertainment experiences,” says John O’Neill, vice president of marketing for Skyworks. “Skyworks’ solutions facilitate seamless connectivity in multimedia platforms, ensuring optimal speed, reliability and sound quality. Further, with our recent addition of intelligent audio technologies, we are expanding our IoT footprint in everything from home audio to kitchen appliances, thermostats, digital assistants, speakers and more.”
According to Juniper Research, the smart audio devices market is expected to exceed $10 billion by 2022, up from an estimated $2.5 billion in 2017, as consumers opt for homes and entertainment systems with increasing levels of connectivity. The proliferation of connected devices across the IoT coupled with artificial-intelligence voice assistant integration, easy smartphone interfacing and a growing number of mobile apps are driving this exponential growth.
Specifically, Skyworks details that Sonos is using high-efficiency, front-end modules from the Company’s portfolio including the SKY85330-11, a complete 802.11b/g/n 256 QAM WLAN RF front-end module (FEM). The device provides all the functionality of a fully matched power amplifier (PA), power detector, low-noise amplifier (LNA), and single-pole, double-throw (SPDT) switch.
Essentially, the SKY85330-11 - an ultra-compact, 16-pin 2.5 x 2.5 mm Quad Flat No-Lead (QFN) package - provides a complete 2.4 GHz WLAN RF solution from the output of the transceiver to the antenna, and from the antenna to the input of the transceiver. The LNA increases the receive sensitivity of embedded solutions to improve range or to overcome the insertion loss of cellular filters (often included for mobile applications). The SKY85330-11 also includes a transmitter power detector with 20 dB of dynamic range, and a digital enable control for transmitter power ramp on/off control.
