TRANSMISSION POWER CONTROL CIRCUIT AND TRANSMISSION DEVICE, TRANSMISSION POWER CONTROL METHOD, PROGRAM
First Claim
1. A transmission power control circuit comprising:
- 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.

Abstract
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 hand; 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.

8. A transmission power control method comprising:
-
performing first power control of an input signal in a low frequency band; converting the input signal after the power control to a high frequency signal; performing second power control of the input signal after the frequency conversion in a high frequency band; and performing power control using only the first power control 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, and performing power control using the first power control and the second power control in a case where the set value of the output power is higher than the minimum value of the output power. - View Dependent Claims (9)
