Abstract
The present invention provides a modified distributed amplifier which is capable of accepting two or more independent inputs and amplifying them without giving rise to a large number of significant intermodulation products. This modified distributed amplifier effectively comprises two or more unmodified distributed amplifiers (as V.sub.11 to V.sub.18 and V.sub.21 to V.sub.28) joined so as to have a common output line (10) but individual, independent, input lines (111 and 211). The join is preferably 'back-to-back' (in a parallel sense) so that the individual distributed amplifiers are in some sort of interleaved arrangement.
