ABSTRACT:
A multimode radio communication terminal includes a tunable source of transmit and/or receive local oscillator signals for transmitting and/or receiving channels of different frequency bands in at least two radio communication systems. The terminal includes, downstream of the tunable source, a switchable frequency changer implementing a fixed frequency change and selectively insertable so that, the source responding directly to the requirements of one radio communication system, insertion of the frequency changer renders it capable of responding to the requirements of another radio communication system using different frequency bands. This is achieved by virtue of a particular change to the frequency produced by the tunable source, effected by the frequency changer.
