GaAs-based broadband wireless and wireline communications component maker Anadigics Inc of Warren,NJ,USA has introduced two new power amplifiers(PAs)optimized for WCDMA,HSPA,and LTE small-cell applications,including picocells,enterprise-class femtocells,and high-performance customer premises equipment(CPE).AWB7122 and AWB7124 operate in the 1805 MHz to 1880 MHz and 728 MHz to 768 MHz frequency band,respectively.
"Carriers are facing mounting pressure to expand network capacity as wireless data consumption continues to increase rapidly,"said Glenn Eswein,director of product marketing for Infrastructure Products at Anadigics."By offering a broad portfolio of high-performance?-Watt and?-Watt linear power amplifiers optimized for the most widely used 3G and 4G frequency bands,Anadigics enables wireless network equipment manufacturers to meet this infrastructure challenge.These PAs provide distinct design,performance and cost advantages for new infrastructure solutions that must deliver higher data throughput,support wider coverage areas,and consume less power."
Anadigics'complete family of small-cell wireless infrastructure power amplifiers leverage the firm's InGaP-Plus technology.AWB7122 and AWB7124 PAs provide 16%and 14.5%efficiency,respectively,to minimize power consumption and offer greater flexibility in the choice of network power sources.Both the AWB7122 and AWB7124 deliver linearity of-47 dBc ACPR at+24.5 dBm output power and 30 dB of RF gain to provide higher data rates with a greater coverage area.The complete family of small-cell power amplifiers is available in a compact,low profile 7 mm x 7 mm x 1.3 mm surface mount package with integrated RF matching to reduce PCB space requirements,says the firm.
Engineering samples of the AWB7122 and AWB7124 are available now for qualified programs.
