Provided is a power amplification device for a satellite communication device with a redundant configuration, in which a plurality of power amplifiers including a standby power amplifier are connected in a ring shape, and which easily switches connection to the standby power amplifier in a case of a failure in active power amplifiers without closing a detour route. The power amplification device for the satellite communication device includes a plurality of basic units (60) each including: a plurality of power amplifiers (51) including at least one standby power amplifier, which are arranged in parallel; a plurality of switches (52) provided to input ends and output ends of the plurality of power amplifiers for switching connection paths; and bypass connection lines (21 to 25) for connecting the plurality of switches in a ring shape, and the plurality of basic units are connected in cascade. |
