ANADIGICS has announced that they are shipping production volumes of the AND0281 and AND0581S WiFi infrastructure front-end integrated circuits (FEICs) to Buffalo for the new WXR-1750DHP router. This high-performance 802.11ac router features three antennas with simultaneous dual-band capabilities and four gigabit wired Ethernet ports.
The Reliance on WiFi networks continues to grow as the number of connected devices rises. ANADIGICS WiFi infrastructure FEICs support this trend by providing an industry-leading combination of integration, efficiency, and linearity to minimize time-to-market and maximize throughput at extended ranges. The WXR-1750DHP 802.11ac router includes HighPower and Beamforming technologies to ensure optimal performance for even the most demanding users.
This family of WiFi infrastructure FEICs leverages the Company’s patented InGaP-Plus™ technology and uniquely designed architectures to combine a high performance power amplifier (PA), low-noise amplifier (LNA) with bypass option and RF switch on a single die. This level of integration greatly improves manufacturability and reliability, while reducing PCB space requirements. The AND0281 is optimized for 2.4 GHz applications with 28 dB linear power gain and -35 dB dynamic error vector magnitude (EVM) at +18 dBm output power. The AND0581S operates in the 5 GHz frequency band with 29 dB linear power gain and -35 dB dynamic error vector magnitude (EVM) at +16 dBm output power. Both FEICs are tuned for optimal performance in 802.11ac applications.
ANADIGICS WiFi Infrastructure FEIC Family Key Facts and Highlights:
