Abstract
A RF transmitter includes a phase-locked loop having an oscillator arranged to output an oscillator carrier and a power amplifier arranged to conduct a power amplifier current. The RF transmitter includes a phase shifter module between the phase-locked loop and the power amplifier 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.
