Abstract :
This paper presents the design of a uniplanar 3-dB hybrid coupler for microwave integrated circuits (MIC) and monolithic MIC (MMIC) applications. The same was developed and tested experimentally using a network analyzer in Sumeru Microwave Communication Lab. Its design and application issues have been widely discussed here with some standard data and graphs. The experimental results for the standard 1.5 lambda circumference uniplanar 180deg hybrid-ring coupler has been found in the standard accuracy range of 3.2 plusmn 0.4 dB coupling, isolation found is greater than 30-dB and the return loss better than 18.2-dB over a 2% bandwidth centered at 1.46 GHz. Also the experimental insertion loss found for this passive component is 0.5 dB at 1.46 GHz. The same has been concluded with its futuristic perspectives for research aspirants and microwave engineers.
