Certain embodiments provide a power amplifying device (1) including: a distribution line (13) which distributes power; a plurality of power amplifying elements (20); a connection line (31); an output line (32); a filter (11); a first directional coupler (12A); and a second directional coupler (12B). The power amplifying elements is provided at a stage subsequent to the distribution line. The connection line is provided at a stage subsequent to each of the power amplifying elements and combines outputs of the power amplifying elements. The output line is connected to the connection line. The filter is placed on the connection line or the output line. The first and second directional couplers are provided at a stage subsequent to the filter. The first directional coupler outputs the high frequency signal transmitted to the output line, to a RF monitor terminal. The second directional coupler outputs the high frequency signal transmitted to the output line, to a level detection detector. |
