Abstract

In this paper, the design of 2-way power dividers based on a branch line coupler with an unequal splitting ratio is designed and realized. A mathematical formulation is elaborated to calculate the impedance of the transmission lines for such a splitting ratio. Three coupler designs with different power splitting ratios are presented, namely 1:4 (-6 dB), 2:1 (3 dB), and 4:1 (6 dB). The couplers are realized using microstrip-based technology and simulated in the full-wave electromagnetic (EM) simulator. The simulated and measured S-parameter results, magnitude and phase at the frequency of 3 GHz indicate that all designed couplers meet the target requirements.
