InGaP based 802.11ac WiFi power amplifier features high linearity

ANADIGICS introduced the high-gain and output-power capable AWL5911 power amplifier (PA) optimized for 802.11a/n/ac WiFi infrastructure and multimedia applications. AWL5911 support multi-user multi-input/multi-output (MU-MIMO) functionality, take advantage of 160 MHz 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. “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. With world-class efficiency, enhanced thermal characteristics and outstanding integration, the AWL5911 supports high-performance multi-user MIMO designs, while reducing BOM costs and minimizing PCB space requirements. We believe that these advantages are being recognized and valued with specification on leading reference designs.”

This InGaP based 802.11ac WiFi power amplifier features high linearity, 33 dB of linear power gain and 1.8% EVM at 22 dBm output power in delivering high-throughput WiFi connectivity in the toughest modulation formats. The AWL5911 also has internal digital PA enable interface eliminating external buffer amplifier, and integrated detector that facilitates accurate power control over varying load conditions (3:1 VSWR).

ANADIGICS says AWL5911 features Ultra-low EVM in the toughest 802.11ac modulation formats, enabling extremely high transmission data rates and the high-accuracy, integrated power detector integrated inside the chip ensure accurate power control over varying load conditions and extend dynamic range

AWL5911 offers higher power efficiency with better thermal characteristics to support MIMO applications.
AWL5911 is having CMOS-compatible control interface to simplify interface to silicon CMOS chips.
Package: Compact 4 mm x 4 mm x 0.8 mm QFN package with RF ports internally matched to 50 Ohms and DC blocked to reduce PCB space requirements

The AWL5911 is available now in volume for production orders.
