1–2.5GHz Multistage Wilkinson 2-way power divider for checkout applications

Abstract

This paper presents the design and development of Multistage Wilkinson 2-way power divider for L & S bands. 3-stage, 2-way Wilkinson power divider with microstrip lines was designed on RT duroid substrate. The measured results show good insertion loss, return loss and isolation better than 20dB throughout the band. These power dividers were successfully used inside Test Selection Matrix (TSM) units of ground checkout and demonstrated the functionality during the navigational payload satellite testing.
