Design, Construction, and Measurement of Branchline Coupler
This letter proposes the design, construction, and measurement of a quadrature coupler at 2 GHz using microstrip technology. The device has the ability to divide the input signal into two, each one ideally 3 dB lower in power, and with a phase difference of 90° between them. The main novelty is the design of four coupler models with different proposals for intersections between the feed lines and the coupler sections. Based on the simulation results obtained, the best performing alternative is selected, and its dimensions are adjusted to operate at the design frequency. After construction the device was validated using a vector network analyzer (VNA).
