摘要

介绍了基于10-30dB和10-500MHz的2kW同轴线变环路型双向耦合器的设计与开发。所开发的耦合器由一条主同轴传输线和两个类似的可动环型耦合器组成。活动环提供可变的耦合幅度。利用这两种方式,可以根据需要采样出不同耦合幅度的正向和反射功率。开发的耦合器已经过测试,发现回波损耗优于- 10dB,隔离优于- 25dB,而耦合范围为- 10dB至- 30dB,频率范围为10至500 MHz。

Design and Development of Coaxial Line Based 2kW, 10-30dB Variable Dual Directional Coupler
Design and development of the 2kW coaxial line based 10-30dB and 10-500MHz variable loop type dual directional coupler has been presented. The developed coupler consists of a main coaxial transmission line with two similar movable loop type coupling arrangements. The movable loops provide variable coupling magnitudes. Using these two arrangements forward and reflected power can sampled out at different coupling magnitude as per desired. The developed coupler has been tested and found providing return loss better than −10dB, isolation better than - 25dB whereas coupling is range −10 dB to −30dB in frequency range of 10 to 500 MHz.
