Abstract

Since the common microstrip power dividers are generally low power devices, in this paper a modified wideband Gysel power divider is proposed, which possesses high power handling capabilities and arbitrary power division. The proposed divider configuration has the provision of heat transfer by resistors connected to the ground plane through vias. The divider structure is devised in such a way that voltage distributions in its two half circuit are symmetrical and the even-and odd- mode analysis may be applied. The method of least squares (MLS) is used to develop an algorithm for its design and optimization, which also incorporates impedance matching among its input and output ports. The widths and lengths of line sections are determined in the design procedure. the proposed power divider and its MLS design algorithm are verified by the electromagnetic softwares.

具有任意功率划分和阻抗匹配的双向Gysel功率分配器的设计与优化
针对普通微带分压器普遍为低功耗器件的特点,本文提出了一种改进的宽带Gysel分压器,该分压器具有较高的功率处理能力和任意功率划分能力。所提出的分压器配置通过通孔连接到地平面的电阻提供热传递。分压器结构的设计使其两个半电路中的电压分布是对称的,并且可以应用偶模和奇模分析。采用最小二乘法(MLS)对其设计和优化提出了一种算法,并考虑了输入输出端口之间的阻抗匹配。线段的宽度和长度在设计过程中确定。通过电磁软件对所提出的功率分配器及其MLS设计算法进行了验证。
