Abstract: Disclosed is an output matching network including a first transmission line and a second transmission line each having one end connected to a respective balanced port of a pair of balanced ports; a third transmission line having one end connected to an unbalanced port; and a fourth transmission line. A first capacitor is connected to the unbalanced port and a load. A second capacitor is connected to an end of the fourth transmission line. The third and fourth transmission lines are coupled to the first and second transmission lines.

Abstract: A wireless communications device may include a controller configured to, in a calibration mode, obtain a first output value of a first power detector after setting a first power amplifier to a first gain and obtain a second output value of the first power detector after setting the first power amplifier to a second gain, wherein the controller may estimate, in a normal mode, output power of a first antenna from an output value of the first power detector, based on a correction coefficient calculated using the first output value and the second output value.
