Abstract: A front-end module for multi-band and multi-mode wireless network system is disclosed. The front-end module includes a diversity switch, two channel-separating devices, a plurality of band pass filters, a plurality of baluns, and a plurality of low pass filters. The number of the band pass filters, the number of the low pass filters, and the number of the baluns are the same as the number of the channels for carrying a radio frequency signal. In addition, all the band pass filters are connected to one channel-separating device while all the low pass filters are connected to the other one, and the baluns are one-on-one connected to the band pass filters.

Abstract: A high-frequency filter whose main structure is formed by stacking a plurality of patterned substrates. The high-frequency filter includes a metal grounding layer, a signal input port, a signal output port, and a plurality of resonator layers having resonators coupled to one another for transmitting signals. By utilizing coupling among resonators located on adjacent layers respectively instead of coupling among resonators on a single layer in the prior planar patterned filter, the structure of the high-frequency filter in the invention can be changed according to process limitations.
