Ruckus chooses TriQuint's two new high-power WLAN modules for fifth-generation 802.11ac applications

Ruckus Wireless Inc of Sunnyvale, CA, USA, which supplies wireless systems for the mobile Internet infrastructure market, has selected two new 5GHz WLAN power amplifiers (PAs) from RF front-end component maker TriQuint Semiconductor Inc of Hillsboro, OR, USA for its top-performing fifth-generation 802.11ac Wi-Fi platforms.

“TriQuint’s high-power WLAN solutions help us deliver best-in-class Wi-Fi systems that give our carrier and enterprise customers unparalleled Wi-Fi performance,” says Ruckus’ co-founder & chief wireless architect Victor Shtrom.

TriQuint says that several other leading Wi-Fi infrastructure OEMs are evaluating its new PAs. The TQP5525 and the TQP5523 deliver what is claimed to be best-in-class linearity to support the technically challenging features of the new 802.11ac Wi-Fi standard, such as multiple-use MIMO with minimal co-channel interference. The new PAs are also designed to support the power and voltage requirements of Power over Ethernet (PoE) applications. The TQP5525 provides 0.5W of output power, while the TQP5523 supports 0.25W to achieve lower power consumption at a lower cost.

“TriQuint continues to deliver advanced 802.11ac Wi-Fi products that enable OEMs to support the users’ increasing demand for faster data throughput,” says James Klein, TriQuint’s VP of Infrastructure and Defense Products. “Our new WLAN power amplifiers are optimized for high data rates and range,” he adds. “According to customer feedback, our TQP5525 delivers up to 3dB higher power output over our closest competition, which would double the operating range of access points delivering 802.11ac throughput,” he claims.

As consumers and businesses increasingly turn to Wi-Fi networks for data and multimedia connectivity, adoption of the 802.11ac standard continues to accelerate, says TriQuint. Wi-Fi devices with the new standard are expected to represent 45% of consumer Wi-Fi equipment shipments by year-end, according to ABI Research. Significant growth in Wi-Fi network deployments is also being fueled by service providers’ plans to off-load and complement data traffic from strained LTE networks, especially in congested urban areas.

The broadband performance of the TriQuint power amplifiers supports the global expansion of available Wi-Fi spectrum as well as the emerging intelligent transportation systems planned in the dedicated short-range communications (DSRC) bands, also known as the intelligent transportation system (ITS) band. Adhering to the strict regulatory emissions required in the automotive industry, these PAs are being implemented on a new generation of intelligent driving systems with consumer-friendly, vehicle-to-vehicle (V2V) communications that will enhance safety on the road, optimize traffic patterns to reduce congestion, and improve the environment by reducing emission and gas consumption.

The PAs operate over what is claimed to be the broadest frequency range (4.9-5.925GHz) available on the market, providing a single solution that supports the expansion of the Wi-Fi spectrum as well as V2V deployments.
