Telecoms ♦ news digest SiC,” says Greg Baker, president and CEO at Nitronex.
Nitronex says its patented SIGANTIC GaN-on-Silicon process is the only production qualified GaN process using an industry standard 4” silicon substrate. This results in a robust, scalable supply chain and positions Nitronex well for the growth expected from emerging GaN markets such as military communications, broadband, RADAR, commercial wireless, satellite communications and point to point microwave.
Fully qualified NPT1015 transistors are now available from stock to 12 weeks, and can be purchased through the Nitronex sales channel and distribution.
Anadigics launches new family of InGaP 802.11 WiFi PAs
The firm’s latest indium gallium phosphide power amplifiers are optimised for infrastructure and multimedia applications
Anadigics has unveiled a new family of 802.11ac power amplifiers (PAs) optimised for WiFi infrastructure and multimedia applications, including access points, routers, media gateways, set-top boxes, and smart TVs.
These PAs deliver a combination of high gain, output power, and linearity to maximise data throughput and ensure reliable transmission of high definition (HD) video at extended ranges.
The company’s new 802.11ac solutions also feature greater integration compared with a typical power amplifier, reducing external component requirements and saving valuable PCB space.
“Anadigics continues to set the RF performance standard for WiFi applications,” says Dave Cresci, vice president of WiFi Products at Anadigics. “Our latest power amplifiers stand out as critical enablers in the expanding use of 802.11ac MIMO technology for WiFi infrastructure in both commercial and residential applications.”
Cresci adds, “They complement and build upon the success of our highly integrated front-end ICs by offering exceptional gain, output power and linearity to deliver higher data rates at greater ranges for an enhanced computing and multimedia user experience.”
Anadigics’ new family of WiFi power amplifiers leverage the Company’s exclusive InGaP-Plus technology and patented design architectures to offer world-class performance and integration.
AWL5905 power amplifier
The first product in this family is the AWL5905 power amplifier, which offers 29 dB of gain and is optimised for 5 GHz WLAN standards, including 802.11a/n/ac. The AWL5905 features an integrated detector that facilitates accurate power control over varying load conditions (3:1 VSWR), as well as a digital PA enable interface that improves ease of use and eliminates the requirement for an external buffer amplifier.
This level of integration includes internal RF matching and is provided in a compact, low-profile 4 mm x 4 mm x 0.8 mm surface-mount package that significantly reduces PCB space requirements. The AWL5905 also combines excellent efficiency and thermal performance, enabling manufacturers to develop multiple input multiple output (MIMO) solutions that consume less power and are more thermally efficient.
Anadigics 802.11ac WiFi Power Amplifier Family Key Facts and Highlights:
High gain and output power levels to ensure optimal performance in infrastructure and multimedia applications
Ultra-low EVM in the toughest 802.11ac modulation formats, enabling extremely high transmission data rates
