研究目的
To present a wideband multilayer balanced-to-unbalanced (BTUB) power divider with inherent common-mode suppression, investigating its working mechanism through even- and odd-mode equivalent circuit analysis, and demonstrating its implementation and performance.
研究成果
The proposed wideband multilayer BTUB power divider demonstrates a bandwidth of 63% with a differential-mode transmission coefficient of -3.45 dB and a common-mode suppression bandwidth of 95%. The performance remains stable with the addition of a shielding cavity, indicating its suitability for connecting wideband multilayer balanced circuits with single-ended circuits.
研究不足
The abstract does not explicitly mention limitations, but the experimental scheme suggests potential challenges in achieving wideband performance and common-mode suppression simultaneously.
