The actual amplifier consists of a transmission line in the dark square. You can distinguish a snake-like structure, consisting of 2000 unit cells containing Josephson Junctions and phase matching elements. The radio-wave signal travels through these while being amplified through mixing with a stronger wave, called the pump wave.
