Design and Prototyping of a Single-Shunt Rectifier with 71% Fractional Bandwidth Having Acceptable Matching on 10 dBm LSSP

In this study, a single-shunt rectifier is proposed, and a 1-GHz broadband rectifier is designed, fabricated, and evaluated. A rectifier is a device used to convert microwaves into DC current for data transmission and reception. First, it was confirmed that the wideband rectifier fabricated using microstrip lines can be matched around 1 GHz. The load resistance was then varied, and the input-output characteristics determined the DC load resistance to be 200 ohm. Next, the frequency response was measured using a DC load resistance of 200 ohm determined by the input/output characteristics. Finally, we calculated the EBW value (bandwidth vs. median bandwidth) using the band above 50% as the frequency band, and achieved 71%.

Automated summary

In this study, a 1-GHz broadband rectifier is proposed, designed, fabricated, and evaluated. The rectifier shows good matching performance around 1 GHz and exhibits a good frequency response with a DC load resistance of 200 ohm, achieving an EBW value of 71%.
