    • In a method and system for producing a plurality of antenna element signals that produce a selected antenna array pattern, first (56) and second (58) input signals are coupled to first (82) and second (84) amplifiers, respectively. The amplitude of said first input signal is modified (68) according to a first factor to produce a first modified signal, and the amplitude of said second input signal is modified (66) according to a second factor to produce a second modified signal. The first input signal is combined (48) with the second modified signal to produce a first combined signal, and the second input signal is combined (50) with the first modified signal to produce a second combined signal. Thereafter, the first combined signal and the second combined signal are amplified using first (82) and second (84) amplifiers, respectively. Next, the amplified signals are transformed with a transform matrix (96) to produce the plurality of antenna element signals.
