Abstract
- The branch-line coupler to be four ports (Input: Port 1, Output: Ports 2 and 3, Isolation: Port 4) distributes the signal applied to Port 1 to Ports 2 and 3 as signals of equal amplitude with a 90-degree phase difference. This paper proposes a variable branch-line coupler to use the dual-impedance (35.35Ω and 50Ω) transmission lines allowing selective signal distribution from Port 1 to Ports 2 and 3, Ports 3 and 4, and Ports 2 and 4. The proposed circuit was fabricated and its performance was verified at a center frequency of 1GHz. The fabricated circuit exhibited valued of -5.0dB and -3.6dB to be outputted to Ports 2 and 3, -5.3dB and -5.0dB to be outputted to Ports 3 and 4, and -3.9dB and -3.8dB to be outputted to Ports 2 and 4, confirming the distribution of signals to any two of the output ports.
