The technology described herein is directed towards microwave attenuators, and more particularly to a cryogenic microwave attenuator device for quantum technologies. In some embodiments, a device can comprise a cryogenic microwave attenuator device. The cryogenic microwave attenuator device can comprise: a housing component and a microwave attenuator chip, wherein the housing component can have thermal conductivity of about at least 0.1 Watts per meter-Kelvin at 1 degree Kelvin. The cryogenic microwave attenuator device can also comprise a microwave connector comprising a signal conductor that is direct wire coupled to the microwave attenuator chip.

A system and method for performing a test for characterizing high frequency operation of PCB boards. More particularly, a system and methodology is provided to implement a time-domain short pulse propagation (SPP) technique on the production line, on large, multi-layer, product-level PCB boards, for large volume testing, by people who are not familiar with advanced, delicate, measurement techniques, who need robust test facilities, and cannot afford the time or expense of other lab-type approaches.
