Abstract: A mobile communication device and an impedance matching method thereof are provided. The mobile communication device includes an antenna, a power amplifier, a tunable matching circuit, a power detection circuit and a controller. The tunable matching circuit determines an output impedance encountered by a radio frequency (RF) signal transmitted by the power amplifier to the antenna when the RF signal enters the tunable matching circuit.
