The at least two physical transmission mediums include a first physical transmission medium arranged to carry a first multiplexed signal including a first IF signal and a reference clock signal. The first IF signal and the reference clock signal are at different frequencies.

Abstract: A supported metallocene catalyst includes a carrier and a metallocene component. The carrier includes an inorganic oxide particle and an alkyl aluminoxane material. The inorganic oxide particle includes at least one inorganic oxide compound selected from the group consisting of an oxide of Group 3A and an oxide of Group 4A. The alkyl aluminoxane material includes an alkyl aluminoxane compound and an alkyl aluminum compound that is present in amount ranging from greater than 0.01 wt % to less than 14 wt % base on 100 wt % of the alkyl aluminoxane material. The metallocene component is supported on the carrier, and includes one of a metallocene compound containing a metal from Group 3B, a metallocene compound containing a metal from Group 4B, and a combination thereof. A method for preparing the supported metallocene catalyst and a method for preparing polyolefin using the supported metallocene catalyst are also disclosed.

Abstract: An electronic device, including a circuit board and a back plate, is provided. The circuit board has a first opening. The back plate includes a bottom portion, a protruding portion, and a column. The protruding portion protrudes from the bottom portion, and the column is located on the protruding portion. In a first direction, the column has a first outer diameter and a second outer diameter. A first width of the first opening is less than the first outer diameter and greater than the second outer diameter to limit the movement of the circuit board. The electronic device of the disclosure limits the movement of the circuit board through the column of the back plate, so as to reduce the number of screws used, thereby achieving the effects of reducing costs and/or reducing man-hours for locking the screws.
