摘要
针对一种可用于星载卫星上的功分网络设计要求,提出了一种立体组合型电桥设计。首先设计180°电桥和3 dB电桥,然后将其组合成功率一分为四、相邻相移相差90°的功分网络。3 dB电桥通过级联方式,扩展了带宽。同时,通过改变三层电路之间铜带搭接的长度来实时调整相位,提高了器件的相位一致性。这种设计方案将电路由平面方式转化为堆叠的立体模型,在结构上得到了优化。所研发的功分网络在P波段内工作良好,各项性能指标均满足设计要求。
Aiming at the design requirements of a power division network that for spaceborne satellites,a threedimensional combined bridge design is proposed.First a 180°bridge and a 3 dB bridge are designed and then are combined into a network with quadripartition power and adjacent phase shifts of 90°.The 3 dB bridges are cascaded to expand their bandwidth.At the same time,the phase is adjusted in real time by changing the length of the overlapped copper tape between the three-layer circuits,improving the phase consistency of the device.This design changes the circuit from a planar type into a stacked three-dimensional model,which is structurally optimized.The developed power division network works well in the P-band,meeting the design requirements.
