4691-0

Pomona Electronics's 4691-0 redefines Between Series Adapters performance for quantum computing and high-frequency trading applications. This ultra-low-latency adapter features patented dielectric materials that reduce signal propagation delay to <3ps/cm while maintaining 50 impedance matching up to 67GHz.The Pin, 0.030" Dia interface incorporates air-dielectric contacts that minimize dielectric loss tangent to 0.0001 at 40GHz. The gold-over-nickel plating ensures consistent contact resistance through 100,000 hot-swap cycles.When converting to Banana Jack configuration, the adapter's skew-matched design maintains <0.1ps intra-pair delay variation. The cryogenic-compatible materials maintain elasticity at 4K temperatures.Available in Black options, the housing features RF-absorbent material that reduces cavity resonance effects above 30GHz. The laser-marked identification withstands liquid nitrogen immersion without degradation.
