Abstract
The six-port correlator is comprised of a power divider and three hybrid couplers. In this paper, the six-port phase correlator using three-arm branch $90^{\circ}$ hybrid coupler were designed with the center frequency of 11.85 GHz. The performances for the six-port phase correlator was analyzed by using ADS2003A tool. Three-arm six-port phase correlator provides more wide dynamic frequency range than that of six-port using the conventional hybrid coupler in range of circa five times, which is range of 10.8 to 12.3GHz (1.5 GHz). The phase errors among the output ports of the six-port phase correlator are below $5^{\circ}$. The six-port Phase correlator was fabricated to evaluate the Performance of the proposed six-port phase correlator. The measured performance of the six-port phase correlator shows the good accordance with the simulation data.
