本研究提出了一种实现紧凑型频率可选双频威尔金森分配器/合成器的技术。为了提供频率选择功能，双频带设备中的带通传输线Transformer（TLT）被替换为可调谐带阻TLT。为了实现这种可调谐器件，可变电容加载的支线滤波器，其紧凑的尺寸提出。基于一个理想的传输线电路的理论发展提供了一个设计过程。所提出的电路进行了演示与威尔金森分配器/组合器在FR 4基板上制作的模拟和测量结果。
A technique for realising a compact frequency-selectable dual-band Wilkinson divider/combiner is presented in this study. To provide a frequency-selection function, the band-pass transmission-line transformer (TLT) in a dual-band device is replaced with a tuneable band-reject TLT. To realise this tuneable device, a variable capacitively loaded spur-line filter is proposed for its compact size. The theory based on an ideal transmission-line circuit is developed to provide a design procedure. The proposed circuits are demonstrated with simulated and measured results of a Wilkinson divider/combiner fabricated on FR4 substrate.
