<p>A power amplifying apparatus (1) is provided with a power amplifier (4), an isolator (5), a resistor (7), and a control circuit (8), which controls output signals of the power amplifier (4) on the basis of electrical signals outputted from the resistor (7). The resistor (7) has a fourth terminal (25a), a fifth terminal (25b), a sixth terminal (28a), a seventh terminal (28b), a first resistor (9), and a second resistor (10). The first resistor (9) is connected to between the fourth terminal (25a) and the fifth terminal (25b), the second resistor (10) is connected to between the sixth terminal (28a) and the seventh terminal (28b), and the second resistor (10) converts heat generated by the first resistor (9) into electrical signals.</p> |
