Design and development of a high power 1×5 splitter/combiner for solid state radar transmitters

This paper presents an L-band non binary six port (1×5) power splitter/combiner utilizing stripline architecture. The detailed design, its implementation and testing is the main focus of this paper. The circuit optimization has been carried out utilizing ADS®. The paper also provides the comparison of simulation and measured results. The measured results indicate that the splitter/combiner has an amplitude balance of ± 0.8 dB with a frequency BW of 500MHz in L-band. Both Input and output VSWR is less than 1.55 while the worst case insertion loss is 0.36 dB. All these results make this combiner/splitter very useful for solid state amplifiers for radar applications.
