Qorvo® announced new Bulk Acoustic Wave (BAW) filters that significantly expand Wi-Fi range and coverage in smart home and enterprise applications. The products enable the maximum power allowed by the Federal Communications Commission (FCC) in the industrial, scientific and medical (ISM) band, delivering more capacity and resulting in improved service quality for consumers, organizations and internet service providers.

The new bandedge and coexistence Wi-Fi filters leverage Qorvo’s BAW technology. They address the stringent thermal challenges of multi-user multiple-input/multiple-output (MU-MIMO) systems, without compromising harmonic compliance and emissions performance. This is critical to achieving reliable coverage across the full allocated spectrum. They also offer significant size reductions to aid designers in creating smaller, more attractive end-user devices for homes and office environments.

According to Christopher Taylor, director of RF & Wireless Components at Strategy Analytics, “A high proportion of the more than 1.5 billion Wi-Fi-enabled smartphones that will ship this year will be able to operate in Western Europe, China, and/or North America using LTE B7, B38, B40 or B41. These bands lie directly above and below the 2400 to 2483 MHz global Wi-Fi band, requiring compact, low temperature-drift filters to prevent interference between Wi-Fi and LTE. Qorvo’s filters meet the needs of the mobile and customer premises markets very effectively.”

Cees Links, general manager of Qorvo’s Wireless Connectivity business, said, “Qorvo has shipped 1 billion cellular coexistence filters optimized for consumer premises use and power handling. These new bandedge and coexistence filters expand our product line and deliver the highest quality of service in high-density environments. Qorvo offers the most compact and most efficient solutions for MU-MIMO configurations of Wi-Fi networks. Designers no longer have to compromise on issues of performance or size, and consumers can connect to more devices across triple the range.”

Bandedge and coexistence filters improve quality of service for Wi-Fi systems. Bandedge filters allow systems to maintain maximum power and capacity for all channels in the Wi-Fi band. Qorvo is the only supplier of bandedge BAW filters at 2.4 GHz. Coexistence filters separate Wi-Fi signals from adjacent LTE signals to avoid interference. When maximum power for all Wi-Fi channels and LTE coexistence is required, both filters can be used together.

Qorvo’s new BAW filters for Customer Premises Equipment (CPE) include the following:

• 885136 World’s Smallest Wi-Fi/LTE Bandedge BAW Filter
