R125052702

The Radiall R125052702 is a 50 Ohm SMA straight plug connector designed for RG-405 (.085" semi-rigid) cable. It features a male pin contact with solder termination for both center conductor and shield. The connector operates from DC to 27 GHz with a maximum VSWR of 1.07 + 0.008 x F(GHz) and insertion loss of 0.03 sqrt(F(GHz)) dB. RF leakage is better than -(90 - F(GHz)) dB. The voltage rating is 335 Veff maximum, with a dielectric withstanding voltage of 750 Veff minimum and insulation resistance of 5000 MOhm minimum.

Mechanically, the connector has a stainless steel body and outer contact with gold plating (0.5 µm over nickel 2 µm), a brass center contact with gold plating (1.3 µm over nickel 2 µm), a PTFE insulator, and a silicone rubber gasket. It is a free hanging (in-line) design with threaded coupling. The recommended mating torque is 100 N.cm, and the mating life is 500 cycles minimum. Cable retention pull-off force is 130 N minimum. The weight is 2.300 g.

Environmental specifications include an operating temperature range of -65°C to +105°C. The connector is packaged in a standard unit of 1 piece. It is designed for use with RG-405 semi-rigid cable and is suitable for applications requiring high-frequency performance up to 27 GHz.
