How Does RF Trends Affect RF Connectors

Time:2019-03-14

When it comes to electronics, technology is rapidly evolving and RF connector manufacturers are struggling to keep up with the times. Whether it's a smart phone, a medical imaging device or a remote sensor that accesses a military satellite system, devices are getting smaller and more complex. At the same time, these devices still need to be rugged, be able to withstand tremendous wear and tear, while providing unobstructed data transfer and collection.


With the new requirements for electronics manufacturing, connector assemblies must be redesigned for these devices. Redesigning is not always easy, because the connectors themselves must be miniature and miniature. In addition, OEM need to offer more customizable design options for their specific application products. Manufacturers are working to meet these ever-changing RF trending needs by providing flexible cables with reliable interfaces, reliable connectivity and portability.

Space and performance are important.In order to explain smaller electronic devices, RF trends are moving toward lower profile components. The device still has complex components, but the size and weight requirements have been significantly reduced to allow for more portability features.

Depending on the type of plug required for the connector, many OEMs are looking for microwave components that can provide high-speed interfaces up to 67 GHz, using a 1.85mm connector that enables high insertion cycles.

Higher frequencies require more data transfer

Device systems now tend to fiber and microwave cables due to the transmission and reception of large amounts of data. These complex systems are evolving from traditional unit GHz performance levels to frequency requirements above 40 GHz.

RF connectors for microwave cables are focused on providing smaller mechanical components that provide higher packing densities while still maintaining superior performance levels. Manufacturers are now focusing on providing high-speed coaxial RF connectors to meet telecom technology needs while keeping in mind the MIL-STD 348B standard RF size requirements that still meet the military interface.

Variable connection and disconnect function

Military system applications sometimes require an RF cable and can be disconnected according to commands. Due to this requirement, the connector may experience problems with disconnection or pin-mating problems at the wrong time. Connector options need to be more flexible to meet these applications without affecting the higher frequency and performance requirements of the system.

Changing the number and position of the pins helps alleviate the problem of ensuring fit while allowing the cable to be disconnected when needed. However, the operating system has turned to 28 GHz or higher that requires higher performance. Current keying schemes only allow frequencies up to 8 GHz.

Keyed coaxial connectors are being introduced for use in electronic devices, allowing for 18 GHz performance while providing keyed position options. This setup minimizes mating issues while providing a more reliable connection to handle systems that experience high shock and vibration in a variety of environments.

Updated design capabilities to reduce compression

When looking at an old coaxial cable, the first thing to notice is the rigid design of the cable at the connector connection point. Termination cables can be compressed when twisted and rotated, affecting connector durability and negatively impacting connector performance.

This RF trend requires a more flexible connector design. Manufacturers are investigating connectors to ensure mating with fail-safe connection nuts while providing cable plugs that allow for different polarizations.

As technology advances, more custom connector solutions are needed


As people's data transmission needs increase, technology is expected to move faster. Connectors need to be able to cope with this challenge without sacrificing performance or operational options. RF connectors need to be designed for the right configuration for a specific product or application, whether for satellite, mobile or electronic warfare applications.
