MINIATURIZED X-BAND STRIPLINE DUPLEXER

Abstract

A prototype design of a 3 port stripline circulator was presented. Low loss performance was achieved over a 400 mc band centered at 9,450 mc. The design of a quadrature stripline 3 db hybrid was discussed. Isolation in excess of 18 db was obtained over a 500 mc band, however, the power split was excessive at the high end of the band. An insertion loss of 0.2 db was obtained on this preliminary unit. A number of diode limiter configurations are presented. By varying the electrical spacing between the two diodes and by adjusting the diode stub impedance, insertion loss values ranging from 0.8 to 1.4 db can be obtained on low level, with 33 to 45 db isolation obtained under forward bias.
