Module simplifies 802.11ac designs in the IoT

By Nick Flaherty at www.flaherty.co.uk

Skyworks Solutions has launched a family of highly integrated wireless networking solutions for mobile and Internet of Things (IoT) ecosystems. 

The SkyOne WiFi suite combines Skyworks' front end radio and 802.11ac technology to provide customers with a comprehensive front-end module in a single placement, compact footprint. Specifically, these new products incorporate all key radio frequency blocks between the Wi-Fi system-on-chip (SOC) and the antenna, avoiding the need for complex RF design challenges, while reducing time to market. 

The SKY85812-11 is dual-band front-end module incorporating a 5 GHz bypass low noise amplifier with single-pole, double-throw transmit/receive switch and a 2.4 GHz bypass low noise amplifier with single-pole, triple-throw switch with Bluetooth port that allows for Wi-Fi antenna sharing. The SKY85812-11 also includes a 2 GHz LTE coexistence filter and diplexer - all designed into a 16-pin 3 x 3 mm package.

The platform significantly improves the Wi-Fi system performance when compared to other standard single chip designs and further mitigates interference with other radios, extending range and increasing throughput to greatly improve the user experience. The SKY85812-11 is currently shipping in flagship platforms globally with a top tier smartphone OEM.
"Today's mobile and IoT devices are now supporting up to 20 bands and require both seamless and robust Wi-Fi functionality to meet growing requirements from carrier offload, voice over IP and other bandwidth-intensive applications," said David Stasey, general manager and vice president of Diversified Analog Solutions at Skyworks. 

According to ABI Research, more than 20 billion Wi-Fi chipsets are expected to be shipped between 2016 and 2021, particularly as Wi-Fi solutions expand beyond their traditional usage applications, frequency bands, device types and performance requirements. They also expect more than 95 percent of devices shipped in 2021 to support 5 GHz Wi-Fi, signifying increased spectrum sharing with cellular technologies.

The SKY85812-11 is currently available for sampling and production.
