摘要:
A method is disclosed to operate a dual mode multi-timeslot RF transmitter, as is an RF transmitter that includes a control unit (100) and a power amplifier (12) that operate in accordance with the method. The method includes, prior to a first timeslot, setting a plurality of control signals (1,2,3,4,5 and 6) for the RF transmitter in accordance with a first modulation format used during the first timeslot; and during a guard period between the first timeslot and a next, temporally adjacent timeslot, setting the plurality of control signals for the RF transmitter in accordance with a second modulation format used during the second timeslot, where the first modulation format differs from the second modulation format. The power amplifier (12) has a fixed gain mode and a variable gain mode used for the two modulation formats, respectively.
