A transceiver and a telecommunication system having a transceiver

A transceiver comprises transmitter means and receiver means, mode means coupled to the transmitter means and the receiver means for simultaneously performing a receiving and transmitting of signals, oscillator means coupled to each of the transmitter means and the receiver means respectively, and frequency divider means coupled between the oscillator means on the one hand and the transmitter means, and receiver means respectively on the other hand. Such a transceiver is capable of operating in full duplex mode without the necessity to adding extra oscillator means to achieve such an operational mode, while in addition this saves components, costs, chip area, power dissipation and weight, which is important for in particular mobile communication applications.
