Description
The DC – 18 GHz SMA Male to SMP Female Cable Assembly by Vinstronics features a 50 – Ohm SMA male connector at one end and a 50 – Ohm SMP female connector at the other. This assembly is designed with a 1.5 mm cable jacket size, offering a static bending radius of 8 mm and a dynamic bending radius of 15 mm. It maintains low attenuation of 4.99 dB/meter at 18 GHz, ensuring signal integrity across its wide frequency range of DC to 18 GHz.
Vinstronics’ W Series cable assemblies are engineered to be low – loss, highly flexible, and capable of handling high – power, high – frequency applications. They exhibit minimal phase change over temperature and flexure, ensuring consistent performance even under dynamic conditions. With a VSWR of less than 1.25 at 18 GHz and time delay matched within ±1 ps, these assemblies are ideal for scenarios requiring phase stability, such as precision test and measurement, aerospace, and defense applications.
