Patent ID: 11956069
Assignee: MURATA MANUFACTURING CO., LTD.
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 2:
3. The multiplexer according to claim 1, wherein:
a frequency gap between the second frequency band group and the first communication band is smaller than a frequency gap between the first communication band and the second communication band,
the first resonant circuit is connected between ground and a third node on the path, the third node being different than the first node and the second node,
the first filter further comprises a second resonant circuit connected between ground and a fourth node on the path, the fourth node being different than the first node and the second node, and
a frequency of a third attenuation pole of the first filter from the common terminal to the first input/output terminal, caused by the second resonant circuit, is closer to the second frequency band group than to the first communication band.
