ABSTRACT:
In a hybrid matrix amplifier array (100), a configurable digital transform matrix (116) is initialize with a matrix of transform coefficients. A plurality of digital input signals (M.sub.1 -M.sub.4) are received at inputs of the configurable digital transform matrix (116). The plurality of digital input signals are transformed to produce a plurality of transform digital signals (A.sub.1 -A.sub.4) using the matrix of transform coefficients. The plurality of transform digital signals are converted to a plurality of transformed analoged signals (206) to produce a plurality of transformed analog signals. The transformed analog signals are amplified (104, 208) to produce amplified transformed signals. Finally, the amplified transformed signals are inverse transformed (102, 210) to produce output signals that correspond to a respective digital input signal (M.sub.1 -M.sub.4). Upon sensing a failure in an amplifier array (104,126) a controller (128) recalls matrix transform coefficients from a memory (130) and write and reconfigures the digital transform matrix (116) to minimize the effects of the amplifier failure at the hybrid matrix amplifier outputs (132).
