宽带双路转动接头的研究
DEVELOPMENT OF TWO WAY ROTARY JOINT WITH WIDE FREQUENCY BAND
-
摘要: 本文介绍一种宽带双路转动接头,两路设计在同一工作频段,在0.7GHz～1.4GHz频带内电压驻波比小于1.3,插入损耗小于0.5dB,两路之间的隔离大于40dB。转动接头采用两点对称激励,套筒式结构,其长度短于/4。该转动接头的结构新颖而简单,加工和调试方便,具有体积小,重量轻的特点,满足了特定的小尺寸要求。Abstract: A wide frequency band two-way rotary joint (in the same frequency band) is described. Its VSWR is less than 1.3 over the frequency range from 0.7 GHz to 1.4GHz, its insert loss is less than 0.50dB, its isolation is better than 40dB. The rotary joint uses two symmetic excitation points and muff structure, and its length is shorter than /4. The structure is simple. Its fabrication and adjustment are easy. And it is light and small. The specified small size requirment is satisfied.
