NoiseTech is introducing a cryogenic switch operating up to 20GHz. The switch consists of a room temperature controller, which interfaces to a computer via USB, and two independent cryogenic switches. Each switch interfaces to the controller via two low-frequency control wires. Unlike other switches, high-current pulses are not required to operate NoiseTech switches. Optional temperature sensor can also be installed on one of the two switches if temperature monitoring capability is desired.
