Sigma Connectivity

Sometimes you need a team.
Sometimes you need one expert.

Every project is different.
Some customers rely on us as an extension of their R&D organization.
Others bring us in to solve a specific technical challenge.
From complete development teams to highly specialized experts, we adapt to the way you work, not the other way around.
That's what engineering flexibility looks like.

Great things happen when strong teams come together. ⚽

Proud to support FC Rosengård and to be part of the match as the Match Host.
And great to have our own Ola Lilja there representing Sigma Connectivity and presenting the Players of the Match!

Congratulations to the Players of the Match on a great game. 👏

Experience isn't measured in years.
It's measured in products.

Some engineers write code.
Others have helped build products that millions of people rely on every day.
At Sigma Connectivity, our engineers bring experience from consumer electronics, medtech, industrial automation, automotive and mission-critical systems.
That knowledge travels with them into every new project.
Because experience isn't something you buy.
It's something you bring.

Vision our engineering.

Your vision deserves more than one engineer.

Behind every engineer is a network of specialists across software, hardware, RF, mechanics, AI, design, manufacturing, and verification.
That means faster answers, broader perspectives, and the confidence to solve even the toughest engineering challenges.
Because great engineering is never built by one person alone.

Need quick EMC validation without the overhead of a full certification project?

Great to welcome SOFF, the Swedish Security and Defence Industry Association to Sigma Connectivity last week.

A valuable visit with good discussions around technology, digital defence and future security capabilities. Thanks for stopping by.

Sound engineering isn't always about making things sound good. In harsh environments, the challenge is often more complex. It's about capturing the right audio, blocking out the wrong audio, and making sure the people who depend on it can focus on their mission, not on how their equipment works.

At Sigma Connectivity, we develop audio solutions for exactly these conditions. This means designing complex acoustic and audio systems for novel form factors, and handling the full integration: audio chipset hardware, software development, measurement, and testing, including developing test methods when standard ones fall short.

Connectivity and RF design are where physics meets product reality.

Antenna placement, signal integrity, interference - these aren't details you optimise at the end of a project. They define what your product can actually do in the real world.

At Sigma Connectivity, RF & antenna engineering is a core capability with state-of-the-art labs and expertise. From antenna simulation and placement to EMC pre-compliance and FCC/CE certification - all under one roof.

Whether you're building a smart wearable, an industrial device, or a mission critical system, getting the RF right early is what separates products that ship from products that stall.
