SMA Plug for RG-402 Semi-Rigid, Rated to 34 GHz
The 901-10707: It is designed specifically for RG-402 (.141" semi-rigid) cable — the cable group is part of the part number's identity, not an afterthought. The connector is rated to 34 GHz maximum frequency, well beyond the typical 18 GHz SMA ceiling, making it suitable for microwave test, instrumentation, and high-frequency interconnect paths where phase stability and low loss matter.
What the 34 GHz Rating Means for the RF Path
The 34 GHz frequency ceiling is the headline spec — it is nearly double the 18 GHz limit of a standard SMA. That headroom means the connector's impedance discontinuity through the interface is low enough to keep VSWR under control at Ku-band and K-band frequencies. For a 50 Ohm system, the solder termination and PTFE dielectric maintain a consistent dielectric constant through the transition. The 500-cycle gold-over-beryllium copper contact ensures the mating interface does not degrade after repeated connects in a test rack or field-service cable assembly.
The cable group is RG-402, the.141" diameter semi-rigid coax — a common size for microwave assemblies where the cable holds its shape after bending. No crimp tool is needed, but a soldering iron with a fine tip and a heat sink on the dielectric are recommended to avoid melting the PTFE.
