A radio frequency module includes an elastic wave filter and a low-noise amplifier that amplifies an RF signal output from the elastic wave filter. An output impedance of the elastic wave filter is positioned, on a Smith chart, closer to a noise matching impedance than to a gain matching impedance, at a frequency of at least one of a low frequency end and a high frequency end of a passband of the elastic wave filter. The noise matching impedance indicates the output impedance where a noise figure of the LNA becomes minimum. The gain matching impedance indicates the output impedance where a gain of the LNA becomes maximum.
