Abstract
A radio transceiver including—an antenna () switch having a control lead (); —a RF and front end circuit () coupled to said antenna switch and operating in at least one 2G mode and at least one 3G mode; —a RF transceiver () coupled to said RF front end and operating in at least a first 2G and a second 3G mode; —a baseband () communicating with a set of peripherals and external devices; The radio transceiver is characterized by the fact that it includes: —control means () for controlling said antenna switch () in a isolated mode; —an programmable adaptive filter controlled by said control means for the purpose of introducing at least one notch for eliminating one corresponding spur. The radio transceiver preferably includes means () for performing, under control of said control means () a FFT computation for the purpose of elaborating a representation, in the time domain, of the different spurs and/or jammers spoiling the received signal when in isolated mode.
