YQ-QP-8A | 8 RF-Port Sample Box

In stockContact us to order

Our compact sample box is designed for few-qubit, high-coherence experiments where speed and throughput are critical.

With 8-RF ports, a 10×10 mm cutout, and a swappable, cost-efficient PCB, it enables fast turnaround and multiple samples on one of our cold fingers.

For drawings and dimensions, see Datasheet. More technical specs and data, on request – feel free to get in touch. 

Key performance metrics are:

  • 8 RF-ports (SMP)

  • Compact, fully light-tight chip enclosure with magnetic shielding

  • RF-PCB with a 10×10 mm chip cutout

  • Low-loss, low-crosstalk 2-layer RF-PCB

  • Non-magnetic components only (PCB, connectors, etc.)

  • Sample box resonance frequencies above 15 GHz

  • Nickle-free gold plating of copper part

Typical Performance

RF frequency DC – 12 GHz
PCB insertion loss < 0.5 dB
PCB return loss > 14.0 dB

PCB crosstalk < -60.0 dB
Box mode freq. > 15.0 GHz
Sample size 10.0 x 10.0 mm
