RADIO FREQUENCY DIRECTIONAL COUPLER AND FILTER

摘要

A coaxial cavity resonator assembly comprising an outer conductor and an inner conductor. The outer conductor including an outer conductor proximal end, an outer conductor distal end, and an outer conductor electrical length that is defined between the outer conductor proximal end and the outer conductor distal end. The center conductor including a center conductor proximal end, a center conductor distal end, and a center conductor electrical length that is defined between the center conductor proximal end and the center conductor distal end. The center conductor proximal end is substantially coplanar with the outer conductor proximal end, the center conductor distal end is substantially coplanar with the outer conductor distal end, and the center conductor electrical length is longer than the outer conductor electrical length by an integer multiple of one-half of one wavelength.
