Abstract

A transmitter arrangement includes a first and a second phase-locked loop, each having a power amplifier. The first phase-locked loop generates a first amplified oscillator signal depending on a first input signal representing a first phase information, wherein a first feedback signal for the first phase-locked loop is derived from the first amplified oscillator signal. Accordingly, the second phase-locked loop generates a second amplified oscillator signal depending on a second input signal representing a second phase information. A second feedback signal for the second phase-locked loop is derived from the second amplified oscillator signal. The transmitter arrangement further includes a summation element to combine the amplified first oscillator signal and the amplified second oscillator signal to an output signal.
