Qorvo® of Greensboro, North Carolina USA has introduced 2.4GHz and 5GHz front-end-modules (FEMs) and bulk acoustic wave (BAW) filters. The company contends that the Wi-Fi FEMs and BAW filters provide the high data throughput and superior thermal efficiency that are required for high-density 802.11ax Wi-Fi connectivity. Qorvo says that the 802.11ax standard will offer substantially increased capacity. This capacity improvement translates into more data, more devices, and more services over different frequency networks.
According to Qorvo, the most recently introduced Qorvo Wi-Fi FEM family supports the 802.11ac and Wave 2 1024QAM thereby laying the foundation for 802.11ax. The family’s 5GHz FEMs offer its highest achievable data rate with more than 1.2 Gbps per stream (with up to eight streams). Qorvo says that these capabilities support the main requirements of 802.11ax, such as extended range and high throughput, multi-user multiple-input/multiple-output (MU-MIMO), as well as denser-capacity Orthogonal Frequency Division Multiple Access (OFDMA) modulation.
Qorvo says its BAW technology targets improvements in band-edge performance, harmonic compliance, and addresses thermal issues for broad power transmission across the full allocated spectrum. The BAW technology thereby maximizes range and reliable data throughput for Wi-Fi applications.
Brad Shaffer, senior analyst, Mobile Devices & Networks at IHS Markit, said, “Qorvo’s Wi-Fi FEM and BAW filter products are examples of the RF components which will be required to enable the developing 802.11ax standard and help Wi-Fi manufacturers realize the benefits of increased capacity and broader coverage indicative of 802.11ax.”
James Klein, president, Qorvo Infrastructure and Defense Products, said, “Our customers are seeing firsthand how Qorvo technology is improving capacity and supporting multiple, high-performance Wi-Fi applications operating simultaneously in the same space. We are expanding our Wi-Fi portfolio across retail, enterprise, service provider and set-top-box markets, and will support the earliest market releases of 802.11ax solutions.”
