摘要

本研究提出一种新型小型化宽频带Wilkinson功率分配器，基于0.18 μ m 1P6M CMOS代工技术。所提出的二维传输线，称为互补导电带(CCS)，取代了传统的微带(MS)线路结构。采用这种CCS结构，这种新型分压器的占用面积比传统的MS Wilkinson功率分压器小约96%。原型，包括输入/输出(I/O)垫，只占用673平方米乘645平方米的面积。新型WPD在8.7 GHz至17.4 GHz范围内的耦合损耗为-5.4 dB，隔离度为+15 dB，回波损耗为-12.5 dB。

A novel miniaturized wide-band Wilkinson power divider employing two-dimensional transmission line

The study proposes a novel miniaturized wide-band Wilkinson power divider, based on 0.18 mum 1P6M CMOS foundry technology. The proposed two-dimensional transmission line, called a complementary-conducting-strip (CCS), replaces the conventional microstrip (MS) line structure. With this CCS structure, the occupying area of this novel divider is approximately 96% smaller than that of the conventional MS Wilkinson power divider. The prototype, including the input/output (I/O) pads, occupies an area of only 673 mum by 645 mum. The new WPD has a coupling loss of -5.4 dB, an isolation of +15 dB and a return loss -12.5 dB from 8.7 GHz to 17.4 GHz.
