摘要： The present invention concerns a RF transmitter (1) comprising:
- a phase-locked loop (20), comprising an oscillator arranged to output an oscillator carrier,
- a power amplifier (40), arranged to conduct a power amplifier current, characterised in that the RF transmitter comprises:
- a phase shifter module (10) between the phase-locked loop (20) and the power amplifier (40), arranged to introduce a phase shift between the oscillator carrier and a harmonic of the power amplifier current, in order reduce a frequency shift of the oscillator carrier due to pushing and/or pulling.
