20 dB SMP Cryogenic Fixed Attenuator DC–18 GHz 2 W VST-QU-SMP200202-18G
P/N: VST-QU-SMP200202-18G
- For compact cryogenic signal attenuation
- 20 dB isolation for sensitive quantum circuits
- SMP interface for high-density integration
- Well suited to dilution refrigerator setups
- Supports precision microwave paths through 18 GHz
Engineering Note
The VST-QU-SMP200202-18G is a 20 dB SMP cryogenic fixed attenuator for compact low-temperature RF paths that require stronger signal reduction while maintaining a controlled 50 Ω impedance path. It supports DC–18 GHz operation with a 2 W power rating, ±1.2 dB attenuation tolerance, and VSWR 1.45:1 max. Its compact SMP interface is suited to cryogenic RF systems, quantum computing assemblies, dilution refrigerator signal chains, and other space-constrained microwave setups where higher attenuation is needed.
