Abstract:
A radio communication device comprising a receive path having first rf-processing means, a transmit path having second rf-processing means, an antenna for receiving and transmitting a radio signal, a transmit-receive switching means coupled between the antenna and the receive and transmit path for switching the antenna to the receive path when the radio communication device is in a receive mode and for switching the antenna to the transmit path when the radio communication device is in a transmit mode, and power supply means for selectively supplying power to the first and second rf-processing means when the radio communication device is in the receive mode or in the transmit mode, respectively, characterised in that transmit-receive switching means is an electromechanical switching means having at least one electromagnetic actuating means for actuating at least one switch comprised in the electromechanical switching means, the actuating means being connected in series with at least one DC-supplied circuit of the receive path or transmit path.
