Radio frequency circuit and communication device

A radio frequency circuit comprising:

• a first amplifying element and a second amplifying element;
• a first transmission line;
• a signal output terminal;
• and
• a first circuit, wherein
• the first transmission line is connected between an output terminal of the first amplifying element and an output terminal of the second amplifying element,
• the first circuit includes
• a first main line, and
• a first auxiliary line,
• one end portion of the first main line is connected to one end portion of the first transmission line, and another end portion of the first main line is connected to the signal output terminal,
• another end portion of the first transmission line is connected to the output terminal of the first amplifying element,
• one end portion of the first auxiliary line is connected to the one end portion of the first main line, and another end portion of the first auxiliary line is connected to ground, and
• a first direction directed from the one end portion of the first main line to the another end portion of the first main line and a second direction directed from the another end portion of the first auxiliary line to the one end portion of the first auxiliary line are the same,
• wherein the radio frequency circuit further comprises:
• a board;
• and
• a power line connected to the first amplifying element and the second amplifying element, the power line being configured to supply power voltages to the first amplifying element and the second amplifying element, wherein
• the first amplifying element and the second amplifying element are arranged on or inside the board, and
• when the board is seen in a planar view,
• the first main line and the first auxiliary line are arranged on a surface of or in an inside of the board in a fifth direction of the second amplifying element, and
• the power line is arranged on a surface of or in an inside of the board in an intersecting part of the fifth direction of the first amplifying element and a sixth direction of the first main line and the first auxiliary line, the sixth direction being orthogonal to the fifth direction.
