  • Radio frequency assembly and a multiport switch having the same
    Patent number: 7463114
    Abstract: An RF assembly of a multiport switch is disclosed. The RF assembly includes an RF cavity housing and a cover. The RF cavity housing includes a common port defined by a cavity in a surface of the RF cavity housing and at least another port defined by a trough in the surface of the RF cavity housing. The trough is connected to the cavity. When covered by the cover, the trough defines a channel connected at one end to the cavity. The distance between opposing surfaces of the RF cavity housing and the cover at a proximal end of the channel is smaller than the corresponding distance of a portion of the channel immediately adjacent the proximal end. A multiport switch having the RF assembly is also disclosed.
