Qorvo’s 802.11ac power amplifiers increase range and throughput for WiFi platforms
Qorvo Inc’s recently launched RFPA55X2 Wi-Fi power amplifier (PA) family is enabling many of today’s leading home and business WLAN networking devices.
The RFPA55X2 Wi-Fi PA family includes the RFPA5512, RFPA5522, RFPA5532 and RFPA5542. The PA product suite offers high power and low power consumption in a design that enables 802.11ac Wave2 features such as eight 80MHz streams, 160MHz streams and multi-user multiple-input/multiple-output (MIMO) technology supporting a variety of devices simultaneously. This allows wireless devices to connect across longer-range access points with ultra-increased data throughput in a high-density user environment under a variety of operating conditions.
Qorvo says that home and business networking device makers turn to its power amplifiers for performance and innovative designs that reduce manufacturing costs. The RFPA5522, for example, provides power-added efficiency of 17% for 802.11ac and more than 20% for 802.11n, resulting in power-added efficiency (PAE) savings of 4-5% that significantly reduce thermal issues in MIMO applications. This reduces the need for thermal compensation devices such as fans and heat-sinks, which in turn enables smaller form factors without a loss in performance.
“Qorvo’s RFPA5522 highly efficient amplifiers deliver the high performance and power efficiency needed for our newest, dual-band 802.11ac consumer routers such as the WRT1900ACS dual-band Wi-Fi Router,” comments Justin Doucette, director of product management at wireless router manufacturer Linksys.
“The RFPA5522 5GHz PA is making next-generation features a reality while helping Linksys to offer the most robust routers that allow users to connect multiple wireless products seamlessly,” says James Klein, president of Qorvo’s Infrastructure and Defense Products group.
