Aimed at the telecommunications industry and based on the company's expertise in the RF field, the new 7/16 coaxial flange receptacle incorporates a design concept and composite materials that significantly reduce the generation of third order passive intermodulation products.
In addition it is easy to install and significantly reduces the total cost of ownership for customers.

A new contact pressure receptacle concept
Radiall has introduced a new receptacle concept whereby the contact pressure on the equipment side is generated by pressure applied by the 7-16 plug. Consequently, when a plug is mated to the receptacle, the tightening torque is diverted by the thread system into an axial force that is applied to the reference plane with the result being that the pressure on both contact junctions is equally distributed. Effectively, the entire force generated by the tightening torque is efficiently transformed and used as an axial force on the contact junctions at the reference plane and panel junction. This improves the intermodulation level and its stability.
Through this concept, the receptacle body is only used as a mechanical support, which guides the reduced mass contact and no longer has an electrical function. This new degree of freedom has the added advantage of enabling the use of different materials that can be selected to offer certain features and meet specific practical needs.

Material selection
Weight reduction: 50%
In deciding on the material for the 7-16 flange receptacle the main considerations were it to be very lightweight, have high corrosion resistance and be colorable to enable color coding. Material selection was also based on:
Material stiffness ? Young?s modulus
Yield limit Ultimate strength
Creeping speed and stress relaxation
Thermal dilatation coefficient
Sensitivity to harsh outdoor environments - corrosion, UV ageing , humidity, etc
Flammability rating
Density
Price
Taking all of these factors into consideration, in-depth analysis revealed that the use of a composite material would meet these requirements and offer considerable advantages, including a weight reduction of more than 50 percent.
Not only does the weight reduction of the components reduce the overall weight of the final module (power amplifiers, filters, etc) but also reduces transportation costs. When the overall cost of ownership is considered, the company claims an improvement in cost at all levels, resulting in a more competitive overall solution.
Components are often required to operate in harsh environments so the composite material's corrosion resistance is a key advantage for many applications.
