High-Performance Cryogenic RF Attenuators for Quantum Computing & Low-Temperature Systems
Engineered specifically for operation inside extreme low-temperature environments such as dilution refrigerators (down to mK ranges), pulse tube coolers, and superconducting quantum computing systems, our Cryogenic RF Attenuators deliver exceptional signal attenuation with minimal thermal noise and negligible magnetic signature.
Covering frequency ranges up to 18 GHz and 40 GHz, these specialized attenuators utilize advanced non-magnetic thin-film technology deposited on high-purity thermal substrates. Available with precision SMA, SMP (push-on), and 2.92mm (K) connectors, they ensure reliable mechanical stability and optimal electrical contact during thermal cycling from room temperature down to cryogenic operating levels.
Key Features & Design Advantages
- Ultra-Low Temperature Compatibility: Engineered to operate reliably at cryogenic temperatures (down to 10 mK / 4K dilution refrigerator stages)
- Non-Magnetic Construction: Manufactured entirely with non-magnetic materials to prevent magnetic flux interference in quantum computing and qubit control lines
- Wide Frequency Range: Standard models available for DC to 18 GHz and DC to 40 GHz high-frequency setups
- Precision Connector Options: Equipped with high-reliability SMA, SMP (ideal for multi-channel rack arrays), and 2.92mm interfaces
- Low Thermal Conductivity Materials: Designed with specialized housing and leads to minimize thermal heat loads from room-temperature stages down to cryogenic stages
- Excellent Attenuation Stability: Stable attenuation values (typically 3dB, 6dB, 10dB, 20dB, 30dB) with minimal temperature-dependent coefficient drift
- Low VSWR & Insertion Loss: Optimized return loss across the entire microwave and mmWave band
