在LTE投资额方面，InfoneticsResearch预测，2013年全球LTE基站投资额为122亿美元，占比无线投资20.6%，2013-2017年CAGR为36%，其中2013-2015年是LTE投资高峰期。


为了抓住这一波商机，全球领先RF器件供应商Anadigics最近针对WCDMA、HSPA和LTE small-cell应用（包括picocell、企业级Femtocell和高性能客户端设备CPE）推出了两款高集成度和高性能功放(PA) AWB7122和AWB7124，它们分别工作在1805-1880MHz和728-768MHz频段，旨在帮助制造商开发紧凑的无线基础设施解决方案，它们消耗更低的功率和提供更高的吞吐量，已覆盖更大的距离。

“随着无线数据消费继续快速上升，”Anadigics基础设施产品营销总监Glenn Eswein说，“通过提供针对大多数广泛使用的3G和4G频段的高性能0.25瓦和0.5瓦线性功放（PA），Anadigics使得无线网络设备制造商能够满足这一基础设施挑战。这些PA可为新的基础设施解决方案提供明显的设计、性能和成本优势，这些基础设施必须提供更高的数据吞吐量，支持更大的覆盖区域，以及消耗更低的能源。”

Anadigics针对small-cell无线基础设施开发的功放采用了该公司独特的InGaP-Plus技术和独创性的设计架构，以提供业界一流的性能和集成。

AWB7122和AWB7124功放分别提供16%和14.5%效率，这可最小化功耗，以及在选择网络电源时提供更大的灵活性。

AWB7122和AWB7124在24.5dBm输出功率和30dB RF增益时提供杰出的-47dBc ACPR，这可在更大的覆盖区域内提供更高的数据速率。

这一系列small-cell功放采用紧凑的低外形7 mm x 7 mm x 1.3 mm SMD封装，内嵌RF终端匹配，从而可减少PCB空间要求。

总而言之，Anadigics small-cell无线基础设施PA的关键特性为：1）支持WCDMA、HSPA和LTE Small-Cell基站所需的高线性度；2）业内一流的效率，可改善可靠性和低成本热设计；3）低噪声，低失真，对外频谱辐射水平很低；4）低晶体管结温实现很高的长期可靠性；5）集成RF匹配电路，用于优化50欧姆系统内输出功率、效率和线性度；6）针对0.25瓦和0.5瓦线性输出功率优化，以支持更宽的应用。

ANADIGICS Expands Small-Cell PA For LTE and WCDMA

【Lead-in】ANADIGICS’ New Power Amplifiers Offer Industry-Leading Combination of Efficiency, Linearity, Output Power, and Thermal Performance for WCDMA, HSPA, and LTE Small-Cell Base Stations

ANADIGICS recently 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). 

The AWB7122 and AWB7124operate in the 1805 MHz to 1880 MHz and 728 MHz to 768 MHz frequency band, respectively, delivering exceptional integration and performance to help manufacturers develop compact wireless infrastructure solutions that consume less power and provide higher throughput with greater coverage.

“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 ¼-Watt and ½-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 Company’s unique InGaP-Plus™ technology and innovative design architectures to deliver industry-leading performance and integration. 

The AWB7122 and AWB7124 power amplifiers 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 exceptional 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.

ANADIGICS Small-Cell Wireless Infrastructure PA Family Key Facts and Highlights:
•    High linearity to support WCDMA, HSPA, and LTE small-cell base stations
•    Best-in-class efficiency for improved reliability and low-cost thermal design
•    Low noise, low distortion for very low spectral emission levels
•    Low transistor junction temperature for high long-term reliability
