Abstract
In one embodiment, a wireless transmission apparatus is disclosed. The apparatus includes a generator unit, an amplitude adjuster unit, a phase adjuster unit, and a setting unit. The generator unit generates an amplitude control signal that minimizes an amplitude difference and a phase control signal that minimizes a phase difference in a state in which a power is set during an OFF period of a switch. The amplitude adjuster unit adjusts an amplitude of a feedback RF signal according to the amplitude control signal during an ON period of the switch. The phase adjuster unit adjusts a phase of a local signal according to the phase control signal during the ON period. The setting unit sets, for a Cartesian loop, a first loop gain when the switch is OFF, and a second loop gain higher than the first loop gain when the switch is turned from OFF to ON.
