90 GHz Between-Series Adapter: 1.0mm Jack to 1.35mm Plug
The TE Connectivity 2385347-1 is a precision between-series RF adapter that converts a 1.0mm jack (female socket) to a 1.35mm plug (male pin). Rated for 50 Ohm systems with a maximum frequency of 90 GHz, this adapter sits at the top end of millimeter-wave interconnect capability — it's built for the test bench or system interconnect where you're pushing into D-band or W-band work. The stainless steel body and PEEK dielectric handle the mechanical and thermal demands of repeated connections in a lab or production test environment.
The 90 GHz max frequency means this adapter maintains a controlled 50 Ohm impedance well into the millimeter-wave region. At these frequencies, the transition between the 1.0mm and 1.35mm interface is the critical point — any geometry discontinuity or plating irregularity kills return loss. The gold-plated beryllium copper centre contacts on both ends keep the signal path clean, and the threaded fastening on both sides ensures the mating interfaces are pulled up tight, not relying on a friction fit that drifts with temperature or vibration.
500 Mating Cycles — Built for Test and Measurement Duty
The gold plating on the centre contacts resists fretting corrosion over those cycles, and the stainless steel body takes the mechanical abuse of threaded coupling without galling. The free-hanging (in-line) format means it floats in the cable run — no panel cutout required, but you'll want to support the cable near the adapter to keep torque off the mating interfaces.
No direct cross-reference or equivalent part number is listed by the manufacturer, so the TE order code is the one to specify.
