The 4846-X series from Pomona Electronics is a line of SMA RF cable assemblies using RG142B/U coaxial cable. These assemblies are designed to provide reliable RF connections in a variety of applications, particularly where space is limited and high-frequency performance is crucial. If you're working on projects involving test equipment, measurement instruments, or radio frequency systems, these assemblies are a go-to solution.

One thing worth noting is their compact design, which makes them ideal for integrating into compact test fixtures or portable RF equipment. Engineers tend to reach for this when they need a small, robust connection that can handle frequencies up to several gigahertz without significant loss or distortion. Another practical benefit is their ease of use; the SMA connector is a standard in the industry, making it easy to connect and disconnect components without specialized tools.

The RG142B/U cable used in these assemblies is known for its excellent electrical performance, maintaining low loss over a wide range of frequencies. This is particularly important in applications where signal integrity is critical, such as in radar systems, communication gear, or precision measurement devices. Overall, the 4846-X series offers a balance of performance and practicality that makes it a solid choice for many RF engineering tasks.
