The TE Connectivity 2388687-1 is an in-series 1.0/2.3 adapter configured as a straight jack-to-jack coupler with female center contacts on both ends. It joins two 1.0/2.3 male-terminated cables or panel jacks in a free-hanging inline connection, maintaining a 50 Ohm characteristic impedance through the transition. The adapter is specified to 110 GHz, placing it in the millimeter-wave band for test instrumentation, microwave backhaul, and high-frequency lab setups where signal integrity through the interconnect matters as much as the cable itself.
Construction and Signal Path
The body is machined from stainless steel, giving it the mechanical rigidity and corrosion resistance needed for repeated coupling in field or production-floor use. Both ends use threaded fastening, so the adapter locks onto the mating connectors without relying on a friction fit.
