Group Capabilities with Steatite

Steatite is the Systems Division of Solid State plc and specializes in designing, manufacturing and supplying rugged computerstactical communication systems and microwave & RF antennas.


Since being acquired by Solid State in March 2021, Active Silicon has been working with Steatite to provide a combined broader portfolio of products and solutions to our joint customer base. We complement the group skills with our high-quality image and video capture products, plus expert design capabilities.

Across the group, we have provided products to highly regulated industries for decades and can certify products to medical, rail, marine and military standards.

Delivering for our customers through combined capabilities

As a group, Steatite has particular expertise in the design and manufacture of custom carrier boards and custom embedded systems. As an agile organization, we are able to respond quickly and precisely to unusual enquiries with very specific requirements.

For example, we provided a unique imaging and computing solution to a rail application with ambitious requirements.

For this project, Active Silicon was able to pool our knowledge with the Steatite Computing team to design, prototype, test and manufacture a completely tailored carrier board and vision system to meet the needs of the customer. The vision system was integrated into a train cab so is subject to extreme vibration, shock, temperature variations and some EMC interference. The final product was therefore certified to meet several standards, including EN50155 for rolling stock.

Building technology for harsh environments – Steatite’s product portfolio

Steatite’s business units specialize in rugged equipment and components for challenging environments. Many products can be further customized for specific applications and requirements.


A rugged fanless industrial computer by SteatiteWith a range of rack mount and fanless computers and accessories, Steatite computers are designed and manufactured to provide reliable operation in demanding environments. Rugged computers are rigorously tested to withstand shock, vibration, dust, moisture and extremes of temperature which would normally cause the rapid failure of conventional computer technology.

Computers, housing, cabling and entire systems can be fully configured or custom-designed for specialized applications.


A communications command and control terminal by SteatiteAs the UK’s only authorized provider of Wave Relay® enabled products, Steatite Communications provides world-leading voice, video and high bandwidth data networks and MIMO communication systems for tactical applications. Enabling crystal clear communication in critical environments, Steatite design and build secure networks for military and civil applications.


An EMC antenna by SteatiteSteatite develops and manufactures high-performance microwave and RF antennas. Expert in-house antenna design, engineering and testing facilities provide solutions for land, marine and airborne applications. Additionally, a repair and refurbishment service adds extra value to the high-spec antenna capabilities.

Custom Power Batteries


Custom Power, another Solid State Group company, offers a range of rechargeable and single use cells and batteries for applications including underwater ROVs, military, medical and transportation. Custom design, batteries for harsh environments and battery management systems are all within the skill set of Custom Power’s expert engineers, and the company is certified to transport lithium batteries worldwide.
