Abstract

A radio-frequency module includes a substrate, a low-noise amplifier circuit being a first amplifier circuit arranged in a first area in the substrate, a power amplifier circuit being a second amplifier circuit arranged in a second area in the substrate, and a duplexer being a component arranged between the first area and the second area in the substrate and having a heat generating property lower than that of the power amplifier circuit. The low-noise amplifier circuit includes a bias circuit configured to generate a bias current dependent on temperature characteristics of a first diode, a voltage generating circuit configured to generate a voltage dependent on temperature characteristics of a second diode as an operating voltage for the bias circuit, and an amplifier circuit configured to operate at an operating point determined by the bias current.
