Anadigics' WiFi infrastructure PA enables Ubiquiti's link distance milestone of 140 miles

Broadband wireless and wireline communications component maker Anadigics Inc of Warren, NJ, USA is shipping production volumes of its AWL5910 power amplifier to Ubiquiti Networks in support of its airFiber 5X carrier backhaul radio. These point-to-point devices leveraged Anadigics' power amplifiers to set a wireless connectivity milestone by linking Los Angeles and Las Vegas, a distance of 140 miles. The real-world applications of this radio address the challenges of wirelessly networking two geographically separated facilities.

"Wireless performance and reliability are advancing at a tremendous pace to sustain the explosive growth in global data demand," says Alex Miller, product marketing manager for WiFi Products at Anadigics. "Anadigics' WiFi infrastructure power amplifiers support this trend by delivering an industry-leading combination of linearity, efficiency, gain and thermal characteristics," he claims. 

The firm's family of 802.11ac WiFi power amplifiers for infrastructure applications leverage its patented InGaP-Plus technology and unique design architectures to offer both performance and integration. Operating in the 4900-5900MHz frequency band, the AWL5910 PA provides 31dB of linear power gain and a low 2.0% error vector magnitude (EVM) at 22dBm output power. This ensures stable, reliable high-throughput WiFi connectivity in the toughest modulation formats, says the firm, enabling extremely high transmission data rates. The 802.11ac WiFi power amplifiers integrate a digital PA enable interface that eliminates the need for costly external circuitry. The AWL5910 also features a high-precision integrated power detector that facilitates accurate power control over varying load conditions as well as extending the usable dynamic range. 

These levels of performance and integration, coupled with the power efficiency and thermal characteristics, enable support of multiple input multiple output (MIMO) designs that consume less power and are more thermally efficient, says Anadigics. With lower current consumption, the firm's WiFi infrastructure power amplifiers also support the stringent power limitations of Power over Ethernet (PoE) equipment.

The compact 4mm x 4mm x 0.8mm QFN package has RF ports that are internally matched to 50 Ohms and DC blocked to reduce PCB space requirements. In addition, a CMOS-compatible control interface improves ease of use.
