Intelligent and green radio transmitters for broadband communication systems

未来的通信网络需要比现在更加无处不在、更加灵活。它们还需要在多标准通信环境中支持对移动性和高吞吐量的大量需求。这增加了无线和卫星通信设备的严格功率和频谱效率需求。因此，未来的无线电系统必须设计成满足上述所有关键能力。虽然多波段接收器和低功率手持终端已经商业化，但在带宽、线性度和功率效率方面，很难在要求的性能范围内设计出用于无线和卫星通信应用的基站和中继器的高功率对应物。

Future communication networks will need to be more ubiquitous and agile than they are today. They will also be required to support the large demand for mobility and high throughput requirements within the environment of multi-standard communications. This adds up to the stringent power and spectrum efficiency needs of wireless and satellite communications equipment. Accordingly, future radio systems have to be designed to meet all the above mentioned critical capabilities. Although multi-band receivers and low-power handheld terminals are commercially available, their high-power counterparts for base stations and repeaters for wireless and satellite communication applications are difficult to design within the required performance, in terms of bandwidth, linearity and power efficiency.
