摘要： A dual frequency feed assembly employing a pair of coaxial circular wave guide cavities, each with respective probe. The higher frequency cavity, e.g. Ku band, is located within the lower frequency, e.g. C band cavity. A common motor is used to drive the two probes which have a common axis A. The lower frequency probe is coupled through the rear wall of the assembly to a rectangular waveguide. The higher frequency probe is also coupled through the rear wall of the assembly but via a coaxial line which is diverted from the axis A to exit beside the lower frequency waveguide. The two rectangular waveguides and the drive motor for the probes are all mounted on the rear of the assembly. In one embodiment of the invention the coaxial line extends from its probe to a housing on the body containing a signal processing circuit board. Connection to that board is made directly eliminating the need for any waveguide transmission line. In other embodiments of the invention, electronic switches, for example, ferrite switches are used in place of rotating probes. The probes may then be fixed and their coaxial lines fixed as well.
