本文介绍了一种宽带300-800 MHz（~ 91%分数带宽）数控可调谐匹配网络的优化设计、特性和应用。该设计采用PIN二极管作为开关元件，并使用集总电抗元件的基本单元的重复结构。在密集和复杂的优化过程之后，在频带（400-700 MHz）的中间达到75%的所有带宽中获得高于60%的史密斯图覆盖率（回波损耗优于10 dB并且损耗低于2 dB）。所制作的可调谐匹配网络的天线失配补偿，天线带宽的扩展和功率放大器的效率提高回退的潜力。
In this paper, the optimized design, characterization and applications of a broadband 300-800 MHz (~ 91% fractional bandwidth) digitally-controlled tunable matching network is presented. The design employs PIN diodes as switching components and a repetitive structure of basic cells using lumped reactive elements. After an intensive and complex optimization process, a Smith chart coverage (return losses better than 10 dB and losses lower than 2 dB) above 60% is obtained in all the bandwidth reaching 75% in the middle of the band (400-700 MHz). The potential of the manufactured tunable matching network for antenna mismatch compensation, antenna bandwidth extension and power amplifier efficiency improvement in back-off is showed.
