Cryogenic technology has emerged as a critical enabling foundation for breakthrough advancements in quantum computing, superconducting electronics and deep-space exploration. As quantum processors and superconducting sensors push toward millikelvin operating temperatures, the performance of RF components deployed in cold zones directly dictates system coherence times, measurement sensitivity, and overall functional reliability. What performs adequately at room temperature often fails under cryogenic conditions, creating an urgent demand for passive components engineered for extreme low-temperature operation.
At RF ONE, we have developed a portfolio of cryogenically-optimized components including fixed attenuators, terminations, adapters and we are actively expanding our cryogenic portfolio as well.
Cryogenic Attenuators
Our Non-Magnetic Cryogenic RF Attenuators are engineered for quantum computing and low-temperature physics applications, addressing the critical challenges of magnetic noise and signal integrity in cryo environments. Constructed entirely from beryllium copper (BeCu) with a nickel-free plating system, these attenuators deliver consistent performance from room temperature down to 4K, making them ideal for integration into multi-stage cooling platforms.
| P/N | Frequency Range | VSWR | Attenuation | Connector |
|---|---|---|---|---|
| RCA18SC-XX | DC-18 GHz | ≤1.25 | 3, 6, 10, 20, 30 dB | SMA |
| RCA27SC-XX | DC-27 GHz | ≤1.3 | 3, 6, 10, 20, 30 dB | SMA |
Cryogenic Terminations
Our Non-Magnetic Cryo Terminations are purpose-engineered for cryogenic applications including quantum computing, low-temperature physics research. Covering DC to 18 GHz (higher frequency available), these terminations feature an all-beryllium-copper construction with nickel-free plating, delivering consistent and reliable signal termination from 4 Kelvin (-269°C) up to 125°C. The off-the-shelf terminations includes SMA and Mini-SMP (SSMP) (Male/Female) configurations to seamlessly integrate with diverse cryogenic system architectures, more to come soon.
| P/N | Frequency Range | VSWR | Connector |
|---|---|---|---|
| RCT18SMAF | DC-18 GHz | ≤1.2 | SMA Female |
| RCT18SSMPF | DC-18 GHz | ≤1.25 | SSMP Female |
| RCT18SSMPM | DC-18 GHz | ≤1.25 | SSMP Male |
Cryogenic Adapters
Designed for seamless integration in ultra-sensitive quantum computing and cryogenic research environments, this series of non-magnetic adapters provide critical interconnect solutions. Featuring high-stability beryllium copper (BeCu) construction with nickel-free underplating, these adapters eliminate ferrous contaminants and magnetic field perturbations that could compromise qubit coherence.
