The TE Connectivity 2081773-1 is a 1.0/2.3 series adapter, Same Series conversion type, in a plug-to-plug configuration with male center contacts on both ends. It is a straight, free-hanging (in-line) adapter with threaded fastening on both sides. The dielectric is polyetherimide (PEI). This adapter is designed for millimeter-wave applications where signal integrity up to 110 GHz is required — the 50 Ohm impedance and 110 GHz max frequency define its RF performance envelope.
The 110 GHz maximum frequency is the headline spec — it tells you this adapter supports D-band and above, suitable for test instrumentation, radar, and high-data-rate communications where lower-frequency adapters would introduce unacceptable insertion loss or VSWR ripple.
The stainless steel body provides corrosion resistance and mechanical robustness for in-line use where the adapter carries the full cable weight. The PEI dielectric offers low loss at millimeter-wave frequencies and holds dimensional stability across the full temperature range.
