A LINC (linear amplification using non-linear component) type amplifier (Fig 4) for a radio transmitter includes a processor 40 generating a pair of phase modulation signals P1, P2 from input signal B(t) and a pair of phase locked loop frequency synthesizers 41 (Fig 5) that have division ratios controlled by the modulation signals to generate respective phase modulated amplified signals V(t). The phase modulated output signals are combined at 42 to form the amplifier output signal for the antenna.
