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 […]
NoiseTech has extended the frequency range of its cryogenic impedance generators to 12GHz. This frequency range enables wider range of applications, particularly for measuring cryogenic noise parameters of low-noise amplifiers for quantum computing/sensing applications. For more information go to the product web pate or contact NoiseTech at support@noisetechmicrowaves.com. Please contact NoiseTech for more information or […]
RF designers often find themselves working on input power matching their circuits to a 50-Ohm signal source. The goal of this task is to develop a matching network that delivers most of the input power to the device. For that, the matching network is optimized such that the reflection coefficient presented by the network to the signal source is low (typically less than 10dB return loss) over the required frequency range.
he following video discusses various useful instruments for developing quantum computers. The part of particular interest starts at 25:20 where cryogenic noise parameter measurements with C-IG0160CT are discussed.
