Abstract
A multiplexer device includes an antenna node connected to an antenna for at least one of receiving and transmitting signals; multiple band pass filters connected to the antenna node, each band pass filter having a different passband; and multiple notch filters connected in to the antenna node and the multiple band pass filters, each notch filter having a different stopband corresponding to one of the passbands of the band pass filters. The notch filters are connected in parallel with one another in order to reduce insertion loss.
