Qorvo Inc of Greensboro, NC and Hillsboro, OR, USA, a provider of RF solutions for mobile, infrastructure and aerospace/defense applications, has launched two 802.11p solutions optimized for high-performance networking in the connected car. Qorvo's 801.11p power amplifier (PA) enhances car-to-car and car-to-infrastructure communication, analysis, and data exchange, helping manufacturers to develop 802.11 systems and applications that enhance automotive safety and improve the driving experience.
"Qorvo is leveraging our broad expertise in high-reliability, high-performance RF solutions to enhance next-generation 802.11p automotive connectivity, with advanced product reliability that is essential to the automotive industry," says James Klein, president of Qorvo's Infrastructure and Defense Products group. "Our newest 802.11p connected car solution has been selected by multiple manufacturers to be featured in their next-generation automotive connectivity reference designs."
The QPA5525Q high-power 802.11p power amplifier module integrates an internally matched three-stage PA, compensated DC biasing circuit, and output power detection. It is claimed to be the most linear solution on the market, enhancing vehicle-to-vehicle and vehicle-to-roadside data transmission for real-time notifications related to traffic congestion management and collision avoidance.
The QPA5525Q is undergoing Automotive Electronics Council (AEC) based testing – specifically AECQ-100 Grade 2 testing – which measures how the product performs between -40°C and +105°C. The QPA5525Q was built for harsh automotive environments and includes a PA that provides high gain at 32dB, what is claimed to be an industry-leading error vector magnitude (EVM) floor, and spectral purity for 802.11p applications. The QPA5525Q is available in sampling quantities and is entering volume production in fourth-quarter 2015.
