(EN) Abstract of the Disclosure A single input, differential output amplifier (50) includes two Gallium Arsenide field effect transistors: one arranged to form a common gate amplifier (55) to provide a non-inverting output (60), and the other arranged to form a common source (65) amplifier to provide an inverting output (61). The input of each FET is connected to receive an input signal simultaneously thereby minimizing phase delay in the differential output signals. In another aspect of the invention, the non-inverting stage (55) is incorporated into the biasing network for the inverting amplifier (65).
