0 dB SMP Cryogenic Fixed Attenuator DC–18 GHz 2 W VST-QU-SMP000202-18G
P/N: VST-QU-SMP000202-18G
- For compact cryogenic signal routing
- Near-through response with minimal added loss
- SMP interface for high-density integration
- Well suited to quantum and dilution refrigerator setups
- Supports precision microwave paths through 18 GHz
Engineering Note
The VST-QU-SMP000202-18G is a 0 dB SMP cryogenic fixed attenuator for compact low-temperature RF paths that require controlled impedance with minimal nominal attenuation. It supports DC–18 GHz operation with a 2 W power rating, ±0.6 dB attenuation tolerance, and VSWR 1.45:1 max. Its compact SMP interface is suited to dense cryogenic microwave assemblies, quantum computing signal chains, dilution refrigerator systems, and other space-constrained low-temperature measurement setups.
