Abstract

The present paper relates to “Branch Line Directional Coupler with Ultra Wide Bandwidth”. The coupler discussed in this paper is capable of operating under the range of ultra-wide frequency and having 2.6 GHz value of operating frequency. Variety of “Micro-wave quadrature hybrids” are recounted for the realizing the stable circuitries, phase shifters, and matched attenuators. Because if convenient designing and execution, the coupler is considered as most popular hybrids. The drawback is it offers restricted bandwidth with huge space necessity. Therefore, the paper deals with a study and examination of the performance based on simulations for “micro-strip branch-line coupler” which is used along with PUFF. After considering analytical/theoretical evaluations using a software, the bandwidth can be enhanced in a range of 3.1- 10GHz with the help of stubs.
