An 11-18 GHz Four-Channel DBR Multiplexer for Electronic Warfare Systems

Abstract : This paper deals with the design of a stripline fourchannel multiplexer that works in the 11-18 GHz band. It allows the splitting of the input spectrum into four 1-GHz bandwidth channels separated by a 1-GHz band. Good-rejections and - wideband phase management are both ensured by 8th-order Dual Behavior Resonator filters directly interconnected and matched through a single-stub network. To facilitate the overall tuning of this device, new electromagnetic discontinuity models were developed and proved to greatly reduce the EM tuning phase. Finally, a 17.1 cm²-size multiplexer was designed in stripline technology to take profit of its low couplings and high isolation between filters. The performed simulations showed good performances (5 dB in insertion loss and more than 60 dB in wideband rejections).
