Qorvo has recently launched the RFPA55X2 Wi-Fi power amplifier (PA) family. This family of power amplifiers include the RFPA5512, RFPA5522, RFPA5532 and RFPA5542. These amplifiers offer high power outputs and low power consumption in an innovative design that enables 802.11ac Wave2 features such as eight 80 MHz streams, 160 MHz 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.
Linksys has integrated the RFPA5522 in to its WRT1900ACS dual-band Wi-Fi Router. This amplifier provides superior power-added efficiency of 17% for 802.11ac and more than 20% for 802.11n, resulting in a 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 heatsinks, which in turn enables smaller form factors without a loss in performance.
Today's consumers demand that home Wi-Fi networks deliver high data throughput to support a broad range of data-hungry, connected applications, like streaming media and gaming, with full coverage for the entire home. These power amplifiers from Qorvo have been designed to enable industry-leading RF performance for high-speed 802.11ac wireless networks for the rapidly expanding number of connected devices in the home and enterprise.
