384AX

Engineered for high-speed test and measurement applications, the 384AX Between Series Adapters from Switchcraft Inc. sets new standards in signal fidelity. This precision adapter maintains 100 differential impedance with less than 1% variation up to 40GHz, critical for 400G Ethernet testing.The XLR, Male Pins, 3 Positions interface features air-cavity contacts that reduce dielectric loss to 0.001dB/mm at 50GHz. The precision-machined BeCu springs maintain constant normal force across temperature extremes.When converting to Phone Jack, Stereo, 6.35mm (0.250", 1/4"), the adapter's skew-matched transmission lines maintain <0.05ps intra-pair delay. The 3D-printed waveguide transition minimizes mode conversion up to 67GHz.Featuring Insulated, Shielded capabilities, this adapter achieves <-60dB return loss up to its rated frequency. The non-magnetic construction prevents interference with sensitive measurement equipment.
