On the way to mobile software defined radio (SDR) terminals, a change of the design philosophy for appropriate microelectronics is necessary. The desired flexibility or reconfigurability must be provided under the constraint of a low power consumption, a low bill of materials and small size. This communication discusses a novel design paradigm for SDR hardware development which will help in paving the way towards reconfigurable or software defined radio. As an example, the authors shall present a novel transceiver architecture which can be implemented in regular CMOS technology. Finally, a comparison of frequency and timing correction strategies in a conventional architecture and in the novel architecture shall be briefly discussed.
