Abstract
A transmission apparatus according to an embodiment includes a power amplifier, an antenna switch, and a control circuit. The power amplifier amplifies and outputs a transmission signal. The antenna switch switches, among at least two or more antennas, an antenna configured to output the transmission signal from the power amplifier. The control circuit performs output power control of the power amplifier when the control circuit outputs to the antenna switch a switching control signal for switching the antenna.
Claims5
A transmission apparatus comprising:
- a control circuit configured to generate a first signal having an in-phase component and a second signal having an orthogonal component of a carrier wave from transmission data and perform amplitude control of the first signal and the second signal when the control circuit outputs a switching control signal for switching to any one of at least two or more antennas, and
- an antenna switch configured to switch the antenna configured to output the transmission data based on the switching control signal.
