RF and mixed-signal semiconductor maker Anadigics Inc of Warren,NJ,USA has launched the AWB7125 and AWB7225 small-cell power amplifiers(PAs),optimized for Band 5 WCDMA and LTE applications including picocells,enterprise-class femtocells,and high-performance customer premises equipment(CPE).
"The rapid growth in mobile data usage is driving carriers to seek cost-effective methods to increase network capacity,especially in dense geographic locations,"says Glenn Eswein,director of product marketing for broadband RF products."Small-cell devices,such as picocells and femtocells,provide carriers with an economical,high-performance solution that can be deployed quickly,"he adds.Anadigics'small-cell power amplifiers have been developed specifically for these applications,and enable wireless infrastructure solutions that are more thermally-efficient,consume less power,enable higher throughput,and provide greater coverage and range,it is claimed.
Performance is optimized for linear output power of 1/4 Watt,+24.5dBm(AWB7125)and 1/2 Watt,+27dBm(AWB7225).RF matching is optimized for output power,efficiency and linearity in a 50 ohm system,and housed in a compact 7mm x 7mm x 1.3mm surface-mount package.Both power amplifiers are compliant with WCDMA,HSPA,and LTE small-cell base-stations operating in the 860-894MHz frequency band.
Anadigics'complete family of small-cell wireless infrastructure power amplifiers is manufactured using the firm's exclusive InGaP-Plus technology to achieve what is claimed to be best-in-class power-added efficiency(PAE)of 15%(AWB7125)and 13%(AWB7225)at rated output power,exceptional linearity of-47dBc ACPR@+/-10MHz offset(10MHz LTE channel bandwidth),and excellent thermal performance(with low transistor junction temperature).
Pre-production samples of the AWB7125 are available now.Engineering samples of the AWB7225 are available now for qualified programs.
Anadigics is exhibiting in booth 3514 at the 2012 IEEE MTT-S International Microwave Symposium(IMS)in Montréal,Canada(19-21 June).Also,on 20 June at 3pm in the Richardson RFPD booth(number 1818),Eswein will give a presentation focusing on small-cell wireless infrastructure power amplifiers.
