Abstract:
An amplifying device of an embodiment includes: a first amplifier amplifying a first component of an input signal; a first output circuit having an input connected to an output of the first amplifier and converting impedance seen from an output of the first output circuit to make the converted impedance seen from the first amplifier; a second amplifier amplifying a second component of the input signal with a bias deeper than that of the first amplifier; a second output circuit having an input connected to an output of the second amplifier, having a longer electrical length than that of the first output circuit part, and converting impedance seen from an output of the second output circuit to make the converted impedance seen from the second amplifier; and a combiner combining the first component amplified by the first amplifier and the second component amplified by the second amplifier.
