摘要

介绍了一种可扩展频率和功率范围的小型整流器。通过采用接地的兰格耦合器和宽带阻抗匹配网络，该整流器在宽频率和宽功率范围内实现了高效率。对整流器的工作机理进行了研究，并进行了实验验证。测量结果表明，在1.0 ~ 2.7 GHz频率范围和5.2 ~ 23.0 dBm功率范围内，整流效率保持在最大值的70%以上。整流器的尺寸为0.28 × 0.16 $\lambda _c^2$。

Compact Rectifier Extended Frequency and Power Ranges Based on Lange Coupler

A compact rectifier with extended ranges of frequency and power is presented. By the adoption of a grounded Lange coupler and wideband impedance matching network, the proposed rectifier achieves high efficiency at wide ranges of frequency and power. Mechanism of the rectifier is studied and the experimental verification is carried out. Measured results exhibit that, within the frequency range of 1.0 – 2.7 GHz and power range of 5.2 – 23.0 dBm, the rectifying efficiency maintains over 70% of its maximum values. The size of the rectifier is 0.28 × 0.16 $\lambda _c^2$.
