研究：TD-LTE芯片售价保持稳定 基频占主要份额

元器件交易网讯 11月15日消息，根据Digitimes研究，一些IC供应商已经开始提供支持TD-LTE的芯片，包括基频芯片、射频芯片、应用处理器、SoC解决方案和软调制解调器，目前为止，基频芯片占TD-LTE芯片出货量的大部分份额。

由于产品标准高，供应商有限，TD-LTE芯片的平均销售价格预计将保持稳定。然而，国内芯片组供应商将逐步提高其硬体规格，并进入该领域，迫使国际品牌供应商专注于更先进的设备，如应用处理器和SoC。

中国移动计划在2014年正式推出TD-LTE服务，已要求芯片供应商提供TD-LTE芯片，该芯片支持五种模式，分别是LTE/LTE FDD、TD-LTE、TD-SCDMA、WCDMA和GSM）以及10个工作频率带。

由于芯片规格较高，因此能满足该要求的芯片组供应商大多是国际厂商，其中包括高通、Marvell科技与联发科。国内大多数IC设计公司，除了深圳市海思半导体，不太可能最初进入中国移动的供应链。（元器件交易网郭路平 译）

Digitimes Research: ASPs of TD-LTE chips to remain stable initially as suppliers are limited

While a number of IC vendors have begun shipping chips supporting TD-LTE, including base band chips, radio frequency chips, application processors, SoC solutions and soft modems, shipments of base band chips account for a majority share of total TD-LTE chip shipments currently, according to Digitimes Research.

China Mobile, while planning to officially launch TD-LTE services in 2014, has required chipset suppliers offer TD-LTE chips supporting five modes (LTE/LTE FDD, TD-LTE, TD-SCDMA, WCDMA and GSM) and also 10 operational frequency bands.

Since the specifications are high, chipset suppliers which can meet the requirements are mostly international players, including Qualcomm, Marvell Technology and MediaTek. Most IC design houses in China, with the exception of HiSilicon Technologies, are unlikely to enter China Mobile's supply chain initially.

ASPs of TD-LTE chips are expected to remain stable initially because of high product standards and limited suppliers. However, local chipset suppliers in China are expected to gradually enhance their hardware specifications and to step into the segment with aggressive pricing later, forcing international brand vendors to focus on more sophisticated devices such as application processors and SoCs, said Digitimes Research.
