This paper presents a simple technique for characterizing multi-port devices. It gives a fast and efficient measurement of the scattering S-parameters of the multi-port device under test (DUT) by measuring 2 of the N ports while other N-2 ports being terminated by broad band antennas as substitution to 50 Omega loads to minimize reflection. This method is applied to the characterization of a 4-port branch-line quadrature hybrid coupler centered at 100 GHz, where direct 4-port measurement are not equipped. Widely available post processing algorithms are then applied which reconstruct the C-2(N) sets of 2-port measured S-parameters into a N port S-parameter for testing purpose. The reconstructed S-parameters match the 4-port simulation well especially in terms of amplitude and phase of the transmissions at both output ports. (AU) | |
