摘要： An acoustic filter device for telecommunication devices includes a first acoustic band pass filter having a corresponding first passband and a second acoustic band pass filter having a corresponding second passband. The second acoustic band pass filter is connected in parallel with the first acoustic band pass filter to provide a combined passband including the first and second passbands.

摘要： A multiplexer device includes at least one acoustic band pass filter connected to a common port, and a hybrid LC/acoustic filter connected to the common port in parallel with the at least one acoustic band pass filter. Each acoustic band pass filter has a corresponding passband and includes multiple acoustic resonators. The hybrid LC/acoustic filter includes at least one acoustic resonator, and has at least one capacitor replaced by a corresponding at least one acoustic resonator, respectively. Each of the at least one acoustic resonator included in the hybrid LC/acoustic filter provides a stopband response when operating in a corresponding acoustic frequency range, and acts as a capacitor when operating in a corresponding non-acoustic frequency range.

摘要： A wide bandwidth multiplexer (MUX) is provided that performs carrier aggregation. The MUX combines at least a first LC filter that acts as a low band filter, at least a first composite filter that acts as a middle band filter, and at least one other LC or composite filter that acts as a high band filter. The wide bandwidth MUX has low insertion loss and provides sufficient attenuation at adjacent edges of adjacent pass bands to prevent overlap between adjacent pass bands.

摘要： A very wide bandwidth composite band pass filter with steep roll-off of a corresponding passband includes a band pass filter and a high-Q acoustic resonator. The band pass filter has a corresponding passband with a very wide bandwidth and a passband roll-off. The high-Q acoustic filter has a corresponding stopband with a roll-off steeper than the passband roll-off, the high-Q acoustic filter being connected in parallel with the band pass filter such that a portion of the stopband is within the passband of the band pass filter, forming a combined passband. A frequency range of the combined passband is approximately the same as a frequency range of the passband of the band pass filter, and a combined roll-off of the combined passband is steeper on one side than the passband roll-off of the band pass filter.
