A Niobium based superconducting amplifier consisting of a series array of 60 vortex flow transistors (VFT) was fabricated and tested. Each VFT consisted of a long Josephson junction biased in the flux flow state, magnetically coupled to a current carrying control line. The topology of the circuit is based on a distributed amplifier configuration. The transresistance of the amplifier in a 50 Ohm environment for frequencies up to 1 MHz was measured.
