Abstract
A wireless transmitter (100) comprises a signal generator (10) for generating a signal, an amplifier (50) for amplifying the signal, and a phase shifting circuit (20) coupled between the signal generator (10) and the amplifier (50) and arranged to shift the phase of the signal to cancel remodulation of the signal generator (10) by the amplified signal.

A wireless transmitter comprising:
- a signal generator for generating a signal;
- an amplifier for amplifying the signal;
- a phase shifting circuit coupled between the signal generator and the amplifier and arranged to shift a phase of the signal to cancel remodulation of the signal generator by the amplified signal.
A method of operating a wireless transmitter, comprising:
- generating a signal with a signal generator;
- amplifying the signal with an amplifier;
- prior to amplifying the signal, phase shifting the signal to cancel remodulation of the signal generator by the amplified signal.
