摘要：
A wideband correlator, with 45% relative bandwidth is proposed at the frequency range of 3.0-5.1 GHz. The structures of the correlator components such as the delay line and the Wilkinson power divider are designed to be realized in transmission line using the Agilent's Advanced Design System. The cm-relator made by using three unique wideband 3-dB couplers. rat-race coupler, and one 3-dB Wilkinson power divider to reach the required bandwidth. The insertion loss, amplitude imbalance, and phase imbalance between ports are presented. The proposed correlator makes compact size better awn correlator of conventional structure.
