Abstract
An amplifying device includes: an amplifying circuit connected between an input terminal and an output terminal and amplifying a signal input in an amplification mode; and a bypass circuit including a filter connected to a bypass path for bypassing the amplifying circuit, wherein the bypass path is in an off-state in the amplification mode and is in an on-state in a bypass mode, and the filter bypasses an input high-frequency signal to ground, in the amplification mode.
