Beschreibung
Zusammenfassung:	A transmission power control circuit includes: a frequency conversion unit that converts an input signal to a high frequency signal; a first power control unit that controls power of the input signal before frequency conversion by the frequency conversion unit, in a low frequency band; a second power control unit that controls power of the input signal after frequency conversion by the frequency conversion unit, in a high frequency band; and a controller that controls power using only the first power control unit in a case where a set value of output power is lower than a minimum value of output power at which power control is possible in the second power control unit, the controller controlling the power using the first power control unit and the second power control unit in a case where the set value of the output power is higher than the minimum value of the output power.
