Inside SRX semi rigid RF cables
The SRX Series semi rigid rf cable features a silver-plated copper center conductor enveloped by a microporous PTFE dielectric. This structural combination ensures a low relative permittivity ranging from 1.49 to 1.73. The external conductor utilizes a solid copper tube. This continuous metal shield provides a rigid form factor while maximizing shielding efficiency to exceed 165 dB.
This copper tube coaxial cable design mitigates signal leakage and environmental phase shifts. The series demonstrates exceptional phase stability across a static temperature range of -50°C to +85°C. Under these conditions, the phase change rate is strictly limited to approximately 1450 PPM, equivalent to 1.45%. Depending on the specific variant, the cut-off frequency extends from 35 GHz up to 60 GHz, supporting high peak power tolerances up to 4 KW.
