Abstract
A method and apparatus for amplifying a signal modulated in amplitude using amplifiers having a given dynamic range corresponding to a limited conduction angle, comprising separating the signal in a first signal and in a second signal depending on the dynamic range of the amplifiers, wherein each of the first signal and the second signal has a corresponding phase assigned based on an amplitude of the signal, amplifying each of the first signal and the second signal using the amplifiers and combining the amplified signals.

A method for amplifying a signal S(t) modulated in amplitude using amplifiers having a given dynamic range (SMIN, SMAX), comprising:
- separating the signal S(t) in a first signal S1(t) and in a second signal S2(t) depending on the dynamic range (SMIN, SMAX) of the amplifiers, wherein each of the first signal S1(t) and the second signal S2(t) has a corresponding phase assigned based on an amplitude of said signal S(t);
- amplifying each of the first signal S1(t) and the second signal S2(t) using the amplifiers;
- and
- combining the amplified signals.
An apparatus for amplifying a signal S(t) modulated in amplitude, said apparatus comprising:
- a pair of amplifiers having a dynamic range (SMIN, SMAX), each receiving a signal to amplify and providing a corresponding amplified signal;
- a flexible signal component separator unit for receiving said signal S(t) and for providing a first signal S1(t) and in a second signal S2(t) to a corresponding one of the amplifiers depending on the dynamic range (SMIN, SMAX) of the amplifiers, wherein each of the first signal S1(t) and the second signal S2(t) has a corresponding phase assigned based on an amplitude of said signal S(t);
- and
- a combiner for receiving and combining the corresponding amplified signals to provide a combined amplified signal.
