Abstract
In a hybrid matrix amplifier array (100), the amplitude of each of a plurality of input signals is measured (132-136, 202). In response to the signal amplitude measurements, an overload condition that will result in an amplifier overload in said hybrid matrix amplifier array is estimated (204, 206, 138). In response to the estimation of the overload condition, the signal amplitude of at least one of the plurality of input signals is modified to prevent the overload condition in the hybrid matrix amplifier array. An overload condition may be estimated if the sum of the amplitudes of the input signals exceeds a threshold (206). In one embodiment, all input signals are modified by proportionately reducing the amplitude of each of the plurality of input signals (304).
