Introduction to RADIALL SMA Flange Receptacles

RADIALL introduces its range of SMA flange receptacles equipped with extended dielectric, available in two primary versions: Standard SMA and Commercial SMA. Designed to cater to a variety of applications, these receptacles come with customizable length options, multiple technological advancements, and tailored finishes to meet specific requirement standards.

Key Characteristics and Technical Data

Both the Standard and Commercial SMA receptacles hold a nominal impedance of 50 ohms and are capable of operating within a frequency range that extends from direct current (DC) up to 18 GHz. The working voltage is rated at 500 V. These flanges are built to sustain a temperature range from -65°C to +165°C, signifying their resilience in diverse operational environments.

When considering durability, the Standard SMA receptacles are designed for 500 mating cycles, while the Commercial SMA receptacles are suitable for up to 100 mating cycles. The retention force of the center contact is 27 N minimum for captivated types for the Standard SMA, while for the Commercial variant, it is 2.8 N minimum. This exemplifies the robustness and reliability of the connections made by these receptacles.

Materials and Finish Options

The construction materials between the two receptacle types differ to accommodate the range of performance requirements and cost considerations. For the Standard SMA, stainless steel is used for the body, beryllium copper for female center contacts, brass for male center contacts and PTFE Teflon for the insulator. The Commercial SMA, on the other hand, employs brass for both body and female center contact, with the same materials for the male center contact and insulator as its counterpart.

Finish options for the receptacles provide further customization capabilities. The Standard SMA receptacle body is available in passivated or gold finishes, while center contacts are gold over nickel. Commercial SMA receptacles arrive in a Barrier Barrier rounded (BBR) or gold finish, and their center contacts have a layer of gold over copper. These finish options not only enhance conductivity and corrosion resistance but also ensure aesthetic compliance to system design.

Technological Advancements

The SMA flange receptacles feature three technologies of center contact captivation and two surface finish types, including passivated and gold for the Standard SMA, and BBR or Gold over Copper for the Commercial SMA. These technologies are aimed at providing reliable contact retention and optimal electrical performance across a broad range of usage scenarios.

In summary, RADIALL offers a versatile array of SMA flange receptacles that can be customized both in terms of physical structure and technological properties, ensuring that they are a suitable choice for diverse industrial applications, while being built to last, thanks to the high-quality materials and finishes that these receptacles employ.
