【摘要】：现代雷达系统正朝着小型化和多功能的方向发展,作为宽带相控阵雷达系统最重要的部件之一,延迟线组件进一步的发展有助于实现收发模块中的瞬时宽带技术。本文提出了一款工作在Ka波段的基于LTCC技术的6路开关延迟线组件,每路延迟线单元由延迟线支路和等损耗直通支路组成,通过驱动电路控制MMIC单刀双掷开关选择通路,可产生最小1λ,最大63λ的延迟量,步进为1λ。延迟支路选用了Ferro A6-M材料,延迟信号通过曲折带状线结构,可以实现组件小型化的同时显著减小色散特性。等损耗支路选用了陶瓷基片。最终实测延迟组件体积仅为84×47×15mm3,并且有优良的驻波系数。
[Abstract]:Modern radar system is developing towards miniaturization and multifunction. As one of the most important components of broadband phased array radar system, the further development of delay line module is helpful to realize instantaneous broadband technology in transceiver module. In this paper, a six-channel switch delay line assembly based on LTCC technology working in Ka band is proposed. Each delay line unit is composed of delay line branch and equal loss straight-through branch. The MMIC single-pole double-throw switch selection path can be controlled by driving circuit, which can produce the minimum 1 位, the maximum 63 位 delay, and the step is 1 位. Ferro A 6 / M material is selected for the delay branch. The delay signal can be miniaturized and the dispersion characteristics can be significantly reduced by the zigzag strip structure of the delay signal. Ceramic substrate is selected for equal loss branch. Finally, the volume of the measured delay module is only 84 脳 47 脳 15mm 3, and it has excellent standing wave coefficient.
