Anadigics Expands WiFi Infrastructure range

New InGaP-Plus PA targets 802.11ac Wave 2 applications

Anadigics today introduced the AWL5911 power amplifier (PA) optimised for 802.11a/n/ac WiFi infrastructure and multimedia applications. 

The new AWL5911 is said to deliver an industry-leading combination of linearity, efficiency, gain and thermal characteristics, while minimising external components.  These performance and integration advantages help 802.11ac Wave 2 solutions enable multi-user multi-input/multi-output (MU-MIMO) functionality, take advantage of 160MHz channels, and make use of an additional transmit spatial stream. 

"The new features available with Wave 2 promise to enrich the experience for WiFi users connected to an expanding array of infrastructure and multimedia devices," said Dave Cresci, president of Anadigics. He added: "Anadigics' family of 802.11ac WiFi power amplifiers is enabling this trend by delivering exceptional linearity, output power and gain to enable ultra-high data throughput."

Anadigics' WiFi PAs use the company's patented InGaP-Plus technology.  The AWL5911 power amplifier delivers 33 dB of linear power gain and 1.8 percent EVM at 22dBm output power to ensure stable, reliable high-throughput WiFi connectivity in the toughest modulation formats. 

The AWL5911 also features an internal digital PA enable interface that eliminates the need for an external buffer amplifier, as well as an integrated detector that facilitates accurate power control over varying load conditions (3:1 VSWR). This level of integration reduces surface mount passive components and simplifies RF design, saving valuable board space, reducing bill of materials, and accelerating time-to-market.
