摘要
介绍了一种宽带双路转动交连,两路设计在同一工作频段,在L波段倍频程内电压驻波比<1.2,插入损耗<0.4dB,两路之间的隔离大于40dB。交连采用两点对称激励、套筒式结构,其长度小于λ/4。该交连结构简单,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。
A wide frequency band two-way rotary joint(some frequency band)is described in this paper. VSWR is less than 1.2 over an octave frequency ranging at L band,the insert loss is less than 0. 4dB,the isolation is more than 40dB. The rotary joint uses two symmetric excitant point and muff constitution and its length is less than λ/4. The constitution is simple. It is easy for producing and adjusting. It is light and small,and meets the requirement for specific and small size.
