Abstract
A radio frequency circuit includes a multilayer substrate, series arm circuits in a first path connecting the input/output terminals (Tand T) on the multilayer substrate, a parallel arm circuit in a second path connecting a node on the first path and a ground, a wiring A on the multilayer substrate connected to the input/output terminal (T) as a part of the first path, a wiring B on the multilayer substrate connected to the input/output terminal (T) as a part of the first path, and a wiring C on the multilayer substrate as a part of the second path. The parallel arm circuit includes an impedance variable circuit, the wiring A and the wiring B in a layer different from the multilayer substrate. When viewed in a plan view, the wiring C does not overlap with the wiring A and the wiring B.
