This compact DC-block isolates both the inner- and outer conductor of any coaxial cable to control the grounding of your electronic measurement setup.

Proper grounding is essential for achieving optimal QPU performance, especially when working with superconducting qubits that are flux-tunable.

Key performance metrics are:

Main application: Controlled grounding of electronic measurement setups
Inner- and outer-conductor DC-block
10 MHz to 9.5 GHz frequency range for RF
Low insertion loss < 0.8 dB
High return loss > 17.5 dB
Max. DC voltage of 100 V
Compact dimensions of 11.4 mm in diameter
