Wideband and Compact Wilkinson Power Divider Utilizing Series Delta-Stub and Folded Stepped-Impedance Transmission Line

Abstract

Dans cet article, un diviseur de puissance Wilkinson est modifié à l'aide d'une ligne de transmission à impédance étagée pliée et à quatre dérivations delta série (FSITL) afin d'obtenir une taille de circuit réduite de 84 % et une bande passante fractionnaire de 116 %. Des dérivations delta série sont utilisées au lieu de dérivations ouvertes pour obtenir une fréquence de décalage optimale et une bande passante plus large. Une ligne de transmission à impédance étagée pliée (FSITL) est utilisée pour obtenir une taille de circuit réduite. Le diviseur de puissance proposé est fabriqué à l'aide d'un substrat RT/duroid 5880 d'une épaisseur de 0,38 mm. La dimension du diviseur de puissance est de 13 mm × 6,5 mm. Le diviseur de puissance proposé a une division de puissance typique de -3 dB et une perte d'insertion inférieure à -1 dB, meilleure que -13 dB d'isolation, moins de -10 dB de perte de retour et des déséquilibres de phase inférieurs à 2° de 1,5 à 3 GHz. Les deux résultats de simulation et de mesure montrent un bon accord.

En este documento, se modifica un divisor de potencia Wilkinson utilizando un tubo delta de cuatro series y una línea de transmisión de impedancia escalonada plegada (FSITL) para lograr un tamaño de circuito reducido del 84% y un ancho de banda fraccional del 116%. Se utilizan tubos delta de la serie en lugar de tubos de derivación abiertos para obtener una frecuencia de desplazamiento óptima y un ancho de banda más ancho. La línea de transmisión de impedancia escalonada plegada (FSITL) se utiliza para lograr un tamaño de circuito reducido. El divisor de potencia propuesto se fabrica utilizando un sustrato RT/duroid 5880 con un espesor de 0,38 mm. La dimensión del divisor de potencia es de 13 mm × 6,5 mm. El divisor de potencia propuesto tiene una división de potencia típica de -3 dB y una pérdida de inserción inferior a -1 dB, mejor que -13 dB de aislamiento, menos de -10 dB de pérdida de retorno y desequilibrios de fase inferiores a 2° de 1,5 a 3 GHz. Los resultados de la simulación y la medición muestran un buen acuerdo.

In this paper, a Wilkinson power divider is modified using four-series delta-stub and folded steppedimpedance transmission line (FSITL) in order to achieve a reduced circuit size of 84% and fractional bandwidth of 116%.Series delta-stubs are used instead of open shunt stubs to obtain an optimum shifting frequency and wider bandwidth.Folded stepped-impedance transmission line (FSITL) is used to achieve reduced circuit size.The proposed power divider is fabricated using RT/duroid 5880 substrate with thickness of 0.38 mm.The dimension of the power divider is 13 mm × 6.5 mm.The proposed power divider has typical power division of -3 dB and insertion loss less than -1 dB, better than -13 dB of isolation, less than -10 dB return loss and phase imbalances less than 2° from 1.5 to 3 GHz.Both simulation and measurement results show a good agreement.

في هذه الورقة، يتم تعديل مقسم طاقة ويلكنسون باستخدام أربع سلاسل من بذرة الدلتا وخط نقل المعاوقة المتدرجة المطوي (FSITL) من أجل تحقيق حجم دائرة منخفض بنسبة 84 ٪ وعرض نطاق ترددي جزئي بنسبة 116 ٪. يتم استخدام بذرة دلتا السلسلة بدلاً من بذرة تحويلة مفتوحة للحصول على تردد تحويل مثالي وعرض نطاق ترددي أوسع. يتم استخدام خط نقل المعاوقة المتدرجة المطوي (FSITL) لتحقيق حجم دائرة منخفض. يتم تصنيع مقسم الطاقة المقترح باستخدام ركيزة RT/duroid 5880 بسماكة 0.38 مم. يبلغ حجم مقسم الطاقة 13 مم × 6.5 مم. يحتوي مقسم الطاقة المقترح على تقسيم طاقة نموذجي قدره -3 ديسيبل وفقدان إدخال أقل من -1 ديسيبل، أفضل من -13 ديسيبل للعزل، وفقدان إرجاع أقل من -10 ديسيبل واختلالات في الطور أقل من 2° من 1.5 إلى 3 جيجاهرتز. تُظهر كل من المحاكاة والقياس توافقًا جيدًا.
