突破性、高效率TriPower™ HV-HBT高功率晶体管
设计和构建无线电系统的网络运营商和制造商面临着两难的困境:如何满足日益增长的高速、高容量连接性需要,同时又能降低运营成本。TriPower™系列RFIC在效率和线性度方面取得了突破,能够支持3G/4G部署的复杂要求,从而解决了上述问题。对整体的Doherty进行配置时,两个120瓦的TG2H214120器件可以提供60瓦以上的平均WCDMA功率,其中集电极效率可达到最高的55%。TriQuint最新的TriPower器件还能轻松地与传统数字预失真(DPD)技术成线性关系,是RF设计工程师的理想选择。TriQuint最新推出的两个高效率TriPower器件[TG2H214120 (120W)和TG2H214220 (220W)]是首个包含了更高频带宽度和更高功率级的产片系列。迅速增长的TriPower系列将扩大该技术在全球不同蜂窝系统中的‘绿色’影响。
发现更多关于TriPower的砷化镓(GaAs)高压异质结双极晶体管(HV-HBT)技术的优点以及TriPower器件如何做到最高效率。除了效率较高之外,TriPower还实现了塔式射频拉远设计,有效地帮助网络运营商通过较大的放大器提高容量,无需相应地增加尺寸或重量。相应地,较高功率的放大器能为蜂窝电话用户提供较高的数据速率。

UMTS-TDD
UMTS-TDD is designed to operate in the following bands:
| Frequencies (MHz) |
Channel Number (UARFCN) |
| 1900 - 1920 |
9512 - 9588 |
| 2010 - 2025 |
10062 - 10113 |

| 1910 - 1930 |
9562 - 9638 |
| 2570 - 2620 |
12862 - 13088 |
Frequency bands deployment
In general, the various UMTS bands are deployed as follows:
- Band I (W-CDMA 2100) in Europe, India, Africa, Asia, Australia (all carriers' metropolitan networks), New Zealand (ITU Region 1) and Brazil (part of ITU Region 2)
- Band II (W-CDMA 1900) in North America and South America (ITU Region 2).
- Band IV (W-CDMA 1700 or Advanced Wireless Services) in the United States (T-Mobile USA) and Canada (WIND Mobile, Mobilicity and Vidéotron)
- Band V (W-CDMA 850) in Australia (Telstra NextG Network), Thailand (True move and DTAC), New Zealand (XT Mobile Network), Brazil, Canada, the USA, Guatemala, Costa Rica, Venezuela, other parts of South America, Israel[2], parts of Asia (ITU Region 2 and ITU Region 3), Poland (Sferia/Aero2 - hspa+ internet only)
- Band VIII (W-CDMA 900) in Europe, Asia, Australia (Optus and Vodafone regional/country 3G networks), New Zealand (ITU Region 1 and ITU Region 3), Thailand (Advanced Info Service) and Venezuela (Digitel GSM)
Multi-band
Today, most mobiles support multiple bands as used in different countries to facilitate roaming. These are typically referred to as multi-band phones. Dual-band phones can cover networks in pairs such as 2100/900 (bands I/VIII) in Europe, Middle East, Asia, Oceania or 1900/850MHz (bands II/V) in North and South America. With the recent release of AWS spectrum (band IV) in North America, the dual-band combo of 1700/2100 is also becoming popular there.
Roaming in Europe works well since all operators use the same bands. In the US this is not really the case[3]. European/Asian tri-band phones typically cover the 900, 1900 and 2100MHz bands giving good coverage in Europe and allowing very limited use in North America, while North American tri-band phones utilize 850, 1900 and 2100MHz for widespread North & South American service and good coverage for worldwide use thanks to the popularity of the 2100MHz spectrum. AWS versions of phones support normally 900/1700/2100 allowing for North American coverage on AWS enabled networks and roaming coverage on 2100MHz and on forthcoming 900MHz overlays in Europe and Asia.
Most UMTS phones also operate on GSM as well, supporting EDGE to ensure data coverage where HSPA still lacks coverage. Note however, that while a phone may have overlapping GSM & UMTS frequency support, being tri-band/quad-band in GSM/GPRS/EDGE does not imply the same support for UMTS, as was the case with many early 2100MHz-only UMTS devices.
Late 2010 there started appearing devices supporting majority of currently used UMTS bands. One of such devices is Samsung Galaxy Tab which uses Infineon PMB 5703[4] UMTS/EDGE RF transceiver chip. Currently shipping versions of Tab only allow to display the supported bands, but not change them. The USSD code used is *#2263#.

集成技术助力基站设计演进
无论网络运营商需要扩大网络覆盖范围,还是推出新服务,系统效率都发挥十分重要的作用。采用远端射频头 (RRH) 技术的小型、高效设计方案正在取代传统高架或单极天线基站。远端射频头可降低固定资产支出、提高效率、便于部署并具有维护方面的特有优势。除支持基站环境下可靠、连续运行现有标准外,RRH器件还必须满足日益严格的尺寸和效率要求。
TriQuint解决方案有助于客户以更少的时间/设计资源解决分立元件的问题,将更多精力专注于系统性能。
各种级别集成器件支持基站演进:
一级
这些器件具有高增益并集成匹配电路。采用这些产品,设计人员可消除上行线路中一级或多级增益,不需要外部匹配电路,有助于减小基板尺寸并降低成本。
二级
这些器件采用单一封装集成多种功能,从而减少整体尺寸,例如,以LO缓冲放大器取代多级放大器或混频器。这些产品有助于减少系统尺寸
三级
这些器件将两级放大器与级间匹配电路组合在一起,消除了放大器之间所需的外部匹配电路,同时降低系统成本和尺寸。
四级
这些产品采用全封装集成。这些模块集成两个放大器、数字步进衰减器、所有匹配器件、偏压扼流圈、正极旁路电容和隔直流电容,为降低成本和更加紧凑的设计提供50 Ohm解决方案。
