15556 所提出的基于非对称耦合线的阻抗匹配器设计方案,通过在耦合线之间引入反馈环节实现宽带匹配,并采用集总元件对传输线进行等效,缩小了电路尺寸、增大了匹配带宽,同时也提高了匹配器的可调节性。 A feedback link was introduced to realize broadband matching, while lumped elements were used to replace the transmission lines. The circuit size was reduced, matching bandwidth was increased anc the adjustability of the matcher was improved.
15557 最后,对实际电路进行加工与测试,测试结果表明所设计的阻抗匹配器相对带宽可达50%以上,尺寸仅为7 mm×10 mm,可用于改善射频链路中元件之间的级间匹配。 Finally, the actual circuit was fabricated and measured. The result indicates that the fractional bandwidth is above 50%,and the size is only 7 mmx10 mm.
