Strategic Consultancy
One of Plextek’s strengths is that it backs its technical implementation skills with consultancy in the form of strategic advice and studies.
Either as a prelude to product development or as a stand-alone activity, Plextek can help clients identify and evaluate opportunities resulting from new markets and technologies. We address a wide range of applications and market sectors within electronics, including automotive, consumer, defence, industrial, medical, security, telecoms, transport and utilities.
The combined experience of our 70+ technical design and manufacturing experts enables us to offer a unique and practical business perspective.
We work for both private and public sector clients including governments, financial investment firms, manufacturers and network operators, assisting with strategic evaluation and decision-making to inform stakeholders, identify risks and improve operational and business effectiveness.
Plextek’s contribution is particularly powerful when clients are seeking to move into new areas of technology or need a fresh view on how existing skills and assets can be exploited in new markets. We bring independent and innovative thinking to business and engineering plans, injecting realism based on having successfully undertaken and delivered several hundred projects.
Sensor Systems
We have engineered systems to measure a great range of different parameters, extracting from radar sensors that provide spatial information about the world through to contact sensors that detect electrical signals on the human body or buried sensors that detect the presence of a parked car. These often require a carefully crafted combination of sensor physics, analogue signal manipulation and digital signal processing.
Signal Processing
Typically, systems use signal processing as the means to extract from, process or prioritise high order data from gathered sensor output for presentation to another system element.
An effective signal processing chain can operate in the real world with the required performance levels and reliability to understand real world effects. We understand this challenge and derive high quality solutions through modelling, mathematics, complex DSP algorithms, hardware and software engineering.
Radar Systems
Plextek has a long heritage in the development of optimal RF solutions specifically designed to meet the needs of high performance Radar and Communication applications. Our multidisciplinary “ground up” approach enables us to clearly identify our client’s requirements and work collaboratively to meet the client needs.
Whether it is adapting and configuring existing technology for a specific desired application or designing new applications entirely; our team, paired with our laboratory and testing capabilities, can give our clients world-leading radar technologies.
