A multiplexer and a method for combining radio frequency (RF) data are provided. The method is described below. The first output management circuit receives first data and second data and determines whether a first power of the first data and a second power of the second data match a default rule. The first output management circuit output first output data including the second data to a combine circuit coupled to the first output management circuit in response to the first power and the second power not matching the default rule. The combine circuit receives multiple output data from the output management circuits respectively and combines the output data to output combined RF data. The output management circuits include the first output management circuit. The output data includes the first output data.

The disclosure provides a multi-link receiving method and a multi-link receiver. The method includes the following. A reference delay range of a j-th data section is determined according to a preset delay time and a receiving time point of the j-th data section of an i-th data frame. In response to determining that the j-th data section is first received among an N number of data sections of the i-th data frame, the reference delay range of the j-th data section is taken as a designated delay range. In response to determining that receiving time points of the data sections of the i-th data frame are each within the designated delay range, the i-th data frame is restored based on the N number of data sections of the i-th data frame.
