HBR SMA Male Connector for RG-402, 0.141" SF/SR, Solder Type
Locally Stocked

SMA solder connectors are used within high performance radio communications systems, such as in 4G and 5G cellular, microwave, mmWave, and aerospace applications.

This connector is used to terminate Semi-Flexible and Semi-Rigid 0.141" cable types such as RG-402, where both the inner conductor and outer braid are soldered to the connector.

As a low-PIM design the connector uses ternary alloys and silver plating to achieve very low VSWR under 3 GHz, and a modest < 1.3:1 VSWR up to 6 GHz.

Recommended Use

This SMA Male coaxial connector is used in high performance and general-precision systems up to 6 GHz. Termination of semi-flexible cables, particularly those operating to 6 GHz must be made with great care and precision.

Cable Suitability

RG-402 Semi-Rigid coaxial cable is a MIL-DTL-17 qualified series providing mode free operation to 34 GHz. The sold tin-plated copper tube effectively provides 100% RF shielding with shielding effectiveness exceeding 110 dB, and enables the dielectric and center conductor to remain precisely spaced. This results in optimum impedance control as well as the lowest possible insertion loss and weight to size ratios.
