High-frequency module

A high frequency module comprising:

• a first external connection terminal;
• a second external connection terminal;
• a filter unit connected between the first external connection terminal and the second external connection terminal;
• a first matching circuit connected between the first external connection terminal and the filter unit;
• and
• a second matching circuit connected between the second external connection terminal and the filter unit;
• wherein
• the first matching circuit and the second matching circuit are inductively or capacitively coupled to each other;
• the filter unit includes:
• a first series connection terminal connected to the first external connection terminal;
• a second series connection terminal connected to the second external connection terminal;
• a plurality of series connection filter devices connected in series between the first series connection terminal and the second series connection terminal;
• and
• a third terminal and a second filter unit;
• and
• the second filter unit is connected between the third terminal and a connection line that connects the first series connection terminal and the filter device to be connected to the first series connection terminal.
