SMA Jack for 26.5 GHz Signal Paths
The 901-10511-3: The threaded coupling provides vibration-resistant mating typical of SMA interfaces, and the solder shield termination ensures a continuous ground path from the connector body to the PCB or cable shield.
The 901-10511-3 and the 901-10511-2 share identical electrical and mechanical specs: both are SMA jacks, 50 Ohm, 26.5 GHz, 500 mating cycles, 170 V rating, flange mount, solder termination. The only difference is packaging — the 901-10511-3 ships in Bulk, while the 901-10511-2 ships in a different package variant. For a BOM line, the choice comes down to the packaging your assembly line accepts; the RF performance is identical.
500 mating cycles is the standard endurance for a gold-plated SMA connector. For a one-time install in a fixed antenna feed or a module port that sees infrequent reconnection, the cycle life is effectively unlimited — the gold plating resists corrosion during storage.
