A Ku Wave Band TR Module Design Based on the Multilayer Arrangement of Wire in PCB

多层板布线技术作为一种重要的组件小型化的技术,应用越来越广泛,通过此技术,可以将TR组件的尺寸做到更小,重量更轻。文章介绍了多层PCB布线技术的相关知识,并利用此技术针对一个Ku波段的TR组件给出了相应的结构设计、电路设计和工艺设计,并最终测得发射端功率输出大于10 W,杂散抑制40 dB左右;接收端接收总增益大于100 dB,噪声系数小于4 dB。

As an important way of minimizing TR module, the multilayer arrangement of wire has been applied more and more widely. The paper presents the related knowledge of multilayer arrangement of wire in PCB. With this technology, a Ku waveband TR module has been designed, including the structure design, the circuit design, and the fabrication technique design. In the end, the TR module has an output power of 10 W, about 40 dB noise wave suppression, and more than 100 dB total gain, less than 4 dB noise figure.
