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.

In this paper, the six-port phase correlator using $90^{\circ}$ hybrid branch-line coupler and three-arm branch $90^{\circ}$ hybrid coupler were designed. The performances for two six-port phase correlators were analyzed by using ADS2003A tool. Three-arm six-port phase collerator provides more wide dynamic frequency range than that of six-port using the conventional hybrid coupler in range of circa five times. Six-port phase correlators were fabricated to evaluate the performance of two six-port phase correlators. The measured performances for two six-port phase correlators show the good accordance with the simulation data.
