The TE Connectivity 1055694-1 is a between-series RF adapter that converts an SMA jack interface to an OSMT jack interface in a straight, in-line body. It belongs to the OSM to OSMT adapter series and is designed for applications where a signal path must transition between these two connector families without a cable splice.
The 6 GHz frequency ceiling means it covers L-band through C-band (including Wi-Fi, 4G/LTE, and many ISM bands), but it will roll off above that; do not use it for a 6.5 GHz signal path and expect the same VSWR. The 100 mating cycle rating is on the low side for a field-service adapter — the gold plating on the beryllium copper contacts is good for corrosion resistance, but the snap-on OSMT side will wear faster than the threaded SMA side. Plan for limited reconnection duty if this adapter lives on a test cable or a frequently swapped panel feed.
Mating and Interface Compatibility
The 1055694-1 mates with any standard SMA jack (female) on the convert-from end and any OSMT jack (female) on the convert-to end. The SMA side uses a threaded coupling — the standard 1/4-36 thread — while the OSMT side uses a snap-on fastening. This is a between-series adapter, so it does not mate with an SMA-to-SMA or OSMT-to-OSMT adapter; its job is specifically to bridge the two interfaces. The free-hanging in-line body has no panel flange or bulkhead mount, so it is meant to sit in-line on a cable or between two panel-mount jacks.
If the application can tolerate a parametric alternative, a current-production SMA-to-OSMT adapter from a different series would be the practical swap, but no pin-compatible direct cross-reference is documented.
