System Design and Consultancy:
| Consultancy More Info |
|
|
RF Engines provides consultancy at the system and detailed implementation level to establish optimal configuration of the down conversion and filtering requirements in the digital domain. Choice of Intermediate Frequency (IF) selection, analogue to digital conversion (A/D) selection and type of process used to perform the signal conditioning, splitting and filtering are complicated issues. Our engineers have extensive experience gained at system level, which enable this complex analysis to be provided.
Optimal FPGA selection and design is also a highly complicated area. Our engineers have years of experience in providing the most compact and efficient designs using the latest design tools available. Support can be provided on device selection and implementation issues.

Whilst there are many Virtex II board designs in the market place, the RFEL Virtex II development board has primarily been designed for flexibility and very high memory bandwidth. This allows the development of very complex, high speed, 'memory intensive' cores such as those developed in the RFEL core architecture range.
Allowing a choice of Virtex II devices (from XC2V3000 to XC2V10000), and a choice of QDR II RAM sizes and types means that the board can be tailor-built to meet a specific application and budget
