A mobile communications device with reduced power consumption

A mobile communication device with - a signal path, a signal path input and a signal path output, - one in the signal path between the signal path input and the signal path output impedance matching circuit interconnected with adjustable impedance for tuning an interconnected with the signal path output variable load impedance, - a control circuit for controlling the impedance matching circuit, - an interconnected in the signal path between the signal path input impedance matching circuit and power amplifier, - sequential transmission time slots in which the power amplifier is working and which are regularly interrupted by time slots in which the power amplifier is not working, in which - a transmit time slot begins at a time T0, - the power amplifier T0 + LVL works only from a time with his full power and LVL 0, - the control circuit adjusts the impedance of the impedance matching circuit within the time interval from T0 to T0 + IE, - the power amplifier only begins to work from a time T0 + LA, - and 0
