In addition to the company's expertise in the design and supply of IP cores, RF Engines have extensive experience in overall system design work.

Our work is concentrated in three main areas :-

•	Military Signal Processing Systems (Radar/Surveillence/EW/Comms)
		DHBF/NCO down converters > FFT/PFT > CORDIC and other post processing.Multi-channel interleaved filter banks. DF systems. Wide band frequency hopping and sweeping signal detection/measurement.
•	Test Equipment Systems
		High quality and flexible spectrum analysis. Analogue IF strip replacement. Wide band real time analysis. Specialist communication signal testing, Bluetooth 802.11x, UWB, etc. Low cost Spectrum analyser on a chip solutions (SOAC).
•	Communications Front End Systems
	.	High quality communications multi-channel filtering front ends. Graychip / Intersil replacement on FPGA.. Wireless communications base station and satellite communications front ends. Flexible user controlled high quality filter banks.

Typical contracts commence with a low cost design study that reviews the system design options and trade-offs. This leads on to agreeing and defining the system specification and timescales for the delivery of the on-chip design. However, system solutions such as the Spectrum analyser on a chip may be available with only minor modifications, meaning reduced risk, cost, and time to market.


The overall system design service is flexible and typically incorporates design considerations including :- the complete system frequency plan, analogue to digital converter device selection, board options, down conversion, system tuning, and the filtering requirements. The channelisation design is optimised to achieve minimum silicon usage. Partitioning of the FPGA and DSP functionality is considered as well as the application processing, which may include averaging, interference detection and cancellation, and demodulation.


Summary

To summarise, RFEL is a solutions provider for advanced electronics project designs that require complex front end, real time, wide and narrow band, flexible signal channelisation.

In addition to a comprehensive range of IP cores, the company also provides detailed system design services for the more specialist applications at the system specification stage, by working in partnership with the prime vendor throughout the project design period.
