IMS 2025 (IEEE MTT-S International Microwave Symposium), the world’s largest gathering and industry exhibition for RF & Microwave professionals, took place in San Francisco, California, this year from 17-19 June.
As emerging fields like quantum computing, deep-space exploration, and ultra-sensitive detection systems push the limits of performance, cryogenic RF and microwave components are taking center stage.
This year’s exhibition featured a range of cryo-compatible technologies—amplifiers, attenuators, cables, and interconnects—designed to operate at extreme temperatures ranging from −150 °C down to near absolute zero (−273 °C). These cutting-edge components are engineered to reduce noise, boost sensitivity, and support the most advanced systems operating at the frontiers of science and technology.
Here are some cryogenic components and solutions featured by companies at IMS 2025:
Cryogenic Dilution Refrigerator Sample Measurement Breadboard System
The QMC-CRYOBRD is a line of off-the-shelf shielded breadboard systems for qubits, TWPAs, JPAs, and quantum processors. Featuring threaded holes, clearance slots for SMA feedthroughs, and light-tight space shielding, they ensure proper mounting and protection of cryogenic superconducting components for optimal performance. Quantum Microwave Components Magnetically Shielded Cryogenic Circulator from 10.50-23.00 GHz.
Cryogenic Low-Noise Amplifier for Quantum Computing Applications
The WCLNA4-8 is an InP HEMT Cryogenic low-noise amplifier that operates in the C-band (4-8 GHz) and is ideal for applications in quantum computing. It offers up to 40 dB gain with ultra-low noise performance. At an operating temperature of 4K, the noise temperature is as low as 3 to 4 K. Each module is rigorously tested and verified, and supplied with performance data at both cryogenic and room temperatures.
Miniaturized Cryogenic Isolators / Circulators for Quantum Computing
These Ultra-compact, cryo-optimized SMT circulators and isolators are set to deliver ultra-low insertion loss (0.35dB at 4K) and exceptional broadband stability down to milli-Kelvin. Double-junction designs reach 36 dB isolation, ideal for protecting qubit fidelity. Engineered for scalable quantum architectures. Made in the USA, these components ease supply chain risks and reduce regulatory uncertainty. The SMT format supports seamless integration. Click here to view Cryogenic Circulators from QuinStar.
Magnetically Shielded Cryogenic Circulator from 10.50-23.00 GHz
The D4C1023YMG is a high-performance broadband cryogenic circulator designed for quantum computing applications. With magnetic shielding and performance that has been optimized in DiTom’s in-house cryogenic test lab at temperatures as low as 4K, this is the de facto circulator solution for quantum computing applications operating from X to K-band.
High-performance Cryogen-free Probe Station
This premium closed-cycle cryocooler-based probe station for on-wafer sample probing cools down unassisted to as low as 4.5 K without the need for cryogens. The CRX-4K can be equipped with probes for RF probing up to 1 GHz and GSG RF/microwave probing up to 67 GHz, with wafers as large as 102 mm in diameter. For heavier-duty cooling power, an optional 2 W CCR cold head can be specified on the station.
Non-Magnetic RF Components and Assemblies
EZ Form offers a wide range of non-magnetic RF components and complete RF assemblies, built to perform flawlessly in environments where magnetic interference just isn’t an option. Whether you’re working in Quantum Computing, Medical Imaging, or other specialty tech applications, their solutions are engineered to keep signals clear and systems sharp.
