Abstract

The superconducting flux flow transistor (SFFT) is a single film, active device generally made from high temperature superconducting (HTS) materials. The device is based on the magnetic control of flux motion, has gain and can operate to over 40 GHz with 3 µm feature size. Existing models are reviewed along with the latest equivalent circuit values derived from S-parameter measurements. Noise performance is compared to that predicted by a relatively simple flux noise model and recent amplifier performance is discussed.
