Broadband wireless and wireline communications component maker Anadigics Inc of Warren, NJ, USA is shipping production volumes of its AND0281 and AND0581S WiFi infrastructure front-end integrated circuits (FEICs) to Buffalo for its new high-performance WXR-1750DHP AC1750-class 802.11ac router, which features three antennas with simultaneous dual-band capabilities and four gigabit wired Ethernet ports, as well as HighPower and Beamforming technologies.
"Reliance on WiFi networks continues to grow as the number of connected devices rises," notes Anadigics' president Dave Cresci. "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."
Anadigics' family of WiFi infrastructure FEICs leverages the firm'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 SP3T Tx/Rx RF switch with Bluetooth (SP2T Tx/Rx switch for 5GHz models) on a single die. This level of integration greatly simplifies RF design and improves manufacturability and reliability, while reducing PCB space requirements and accelerating time-to-market, says Anadigics.
Operating at frequencies of 2400-2500MHz, the AND0281 is optimized for 2.4GHz applications with 28dB linear power gain and -35dB dynamic error vector magnitude (EVM) at +18dBm output power. Operating at frequencies of 4900-5875MHz, the AND0581S operates in the 5GHz frequency band with 29dB linear power gain and -35dB dynamic EVM at +16dBm output power. Both FEICs are tuned for optimal performance in 802.11ac applications. In particular, ultra-low EVM in the toughest modulation formats enables extremely high transmission data rates, while high gain and output power levels ensure optimal performance in infrastructure and multimedia applications.?
The compact 3mm x 3mm x 0.6mm QFN package also incorporates high-precision, integrated power detector (to ensure accurate power control over varying load conditions and to extend dynamic range) and RF ports (internally matched to 50 Ohms and DC blocked) to reduce PCB space requirements.
