A filter with a low-noise amplifier includes: two amplification circuits, a first 3-dB hybrid circuit which is connected to an input side of the amplification circuits, a second 3-dB hybrid circuit which is connected to an output side of the amplification circuits, and a filter which is connected to one input terminal of the first 3-dB hybrid circuit. The other input terminal of the first 3-dB hybrid circuit is subjected to matched termination. A signal is inputted to an input terminal of the filter and is outputted from one output terminal of the second 3-dB hybrid circuit and the other output terminal of the second 3-dB hybrid circuit is subjected to matched termination.
