寬帶雙路轉(zhuǎn)動接頭的研究
DEVELOPMENT OF TWO WAY ROTARY JOINT WITH WIDE FREQUENCY BAND
-
摘要: 本文介紹一種寬帶雙路轉(zhuǎn)動接頭,兩路設(shè)計在同一工作頻段,在0.7GHz～1.4GHz頻帶內(nèi)電壓駐波比小于1.3,插入損耗小于0.5dB,兩路之間的隔離大于40dB。轉(zhuǎn)動接頭采用兩點對稱激勵,套筒式結(jié)構(gòu),其長度短于/4。該轉(zhuǎn)動接頭的結(jié)構(gòu)新穎而簡單,加工和調(diào)試方便,具有體積小,重量輕的特點,滿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. -
