METHOD FOR CALIBRATING A BAND REJECTION FILTER OF A TERMINAL AND MULTISTANDARD TERMINAL WITH CALIBRATED BAND REJECTION FILTER

摘要

The present invention relates to the calibration of a band- rejection filter of a terminal and a multimedia mobile terminal capable of transmitting and receiving signals compliant with several standards in the UHF band. It comprises: a receiver (102) receiving a first signal compliant with a first standard in a first band of frequencies comprised between the frequencies f1 and f2, with f2 f1, a first transmitter (202b) capable of transmitting a second signal compliant with a second standard in a second band of frequencies comprised between the frequencies f3 and f4, with f3 f2 and f4 f3, a band-rejection filter (101 b), upstream of said receiver, in order to, when said first transmitter transmits a second signal, filter said second signal, said band- rejection filter comprising at least one variable element enabling the rejection frequency of said band-rejection filter to be adjusted onto the frequency of said second signal by varying the control voltage of said variable element.
