SMA Jack Assembly Kit for RG-Type Cables
The 901-9602-3: This kit supplies all six components needed for a single cable termination: the connector body, a center contact, a ferrule, a heat shrink sleeve, an insulator, and a coupling nut. The 50 Ohm impedance and 12.4 GHz maximum frequency make it a standard choice for RF signal paths in test equipment, antenna feeds, and wireless infrastructure where the cable run is RG-174, RG-179, RG-187, RG-188, or RG-316.
50 Ohm Impedance and 12.4 GHz Bandwidth
The 50 Ohm characteristic impedance matches the standard for most RF test and communications systems, so the connector introduces no impedance step that would reflect signal energy. The 12.4 GHz upper frequency limit covers L-band, S-band, and most of C-band — enough for cellular backhaul, Wi-Fi, and many radar applications. Above that frequency, the SMA interface geometry begins to support higher-order modes, so the 12.4 GHz rating is a practical ceiling for single-mode operation.
This kit is built for the RG-174, RG-179, RG-187, RG-188, and RG-316 cable group — all 50 Ohm flexible coax types with a nominal outer diameter around 2.5 to 2.8 mm.
Durable Construction for Field and Lab
The stainless steel body with gold finish resists corrosion and provides a low-resistance ground path through the threaded coupling nut. The beryllium copper center contact with gold plating delivers consistent electrical performance over 500 mating cycles — enough for repeated test connections or field-service swaps. The weatherproof ingress protection means the mated pair can be used outdoors or in washdown areas without sealing tape or boots, as long as the cable entry is also sealed.
Operating Temperature Range
The PTFE insulator holds its dielectric constant across that range, so the impedance stays stable.
