The problem of synthesis of array structures capable of providing a highly linear voltage response has been studied in detail. Two possible approaches have been suggested. The first one supposes synthesis of the series array by means of interferometer cells with sinusoidal responses. The second approach supposes synthesis of highly linear differential array structures by means of interferometer cells with vertical bar sin(x)vertical bar- like voltage responses at bias current I-b = I-c. When the interferometer cells are replaced by parallel arrays, a high- performance parallel - series differential structure is formed. The traveling wave amplifier design is suggested to avoid limitations resulting from the distributed nature of long series arrays.
