Cellular infrastructure prototype development
The Brief
This development required real-time control and monitoring of high power circuitry in reaction to a constantly varying input modulation envelope.
The Solution
We collaborated with Nujira’s engineering team to create an affordable and high-quality prototype solution that could be further developed into a version suitable for mass production. To achieve this, they engaged with system architects, FPGA, DSP, and experts in software and hardware – working together to design a robust and effective solution.
Analysis of problem, specification development, and implementation and testing of solution.
Embedded processor/FPGA control and monitor loop circuitry for low power, compact, low cost design, including power sequencing and high resolution DACs.
Worked with FreeRTOS on an ARM7 LPT21xx processor to write full C code device and function drivers, and complex multi-tasking state machine to enable controlled/monitored power-up/down sequences.
Developed a host interface; a script-based host emulation tool used in design evolution, DVT and production test; and an ActiveX interface for interface to production test applications.

Fen Technology has been a valuable addition to the Xaar engineering team. They have allowed our engineers to remain focused on core developments and at the same time giving us the confidence that we can take on a greater developmental roadmap whilst retaining full intellectual ownership of all our product designs.
Fen was able to hit the ground running and, using their considerable skills and experience in Bluetooth product development, was able to quickly bring Securecom to a point where we were able to demonstrate a complete solution. As a result, we have asked Fen to continue to support Securecom towards Bluetooth Qualification and full production.
Fen has impressed us with how they have created a solution that has met both EMT’s needs of integration with our existing infrastructure and way of working, and provided a high quality feature enhancement to our product range.
Fen Technology’s skills and experience were a key factor in selecting them as a development partner. Fen’s ability to de-risk the design process was a significant benefit to us during the product development.
Fen Technology proved a worthy partner in supporting Nujira at a critical stage in the development of our leading-edge power amplification technology for the cellular infrastructure market. Fen’s experience and maturity of approach has given us the confidence to entrust them with a range of tasks that were integral to our early-stage development.
Fen’s engineers have done an excellent job in creating a sophisticated, flagship product that outperforms the competition with respect to price/performance ratio. The development methodology is mature and leads to qualitatively solid software, while Fen’s approach has been always persistent and professional.
