We have Gerbers and BOMs for a small UWB radar receiver and transmitter (1 – 100 MHz) used for ground penetrating radar applications. The boards were designed around 2007, and many of the specific parts no longer are in production (CPLD, memory, even some resistors and diodes). We require an RF engineer to go through the BOM and update the list with modern components easily sourced from DigiKey, Newark, Mouser, etc, without a significant re-design of the boards themselves.
Ideally, the successful candidate would also be able to re-write the FPGA firmware to accommodate a faster ADC chip. We are currently using an 80 MSPS 14 bit ADC (AD9245BCPZ-80), which is the fastest in that specific form factor. Ideally, we would like to go as high as 180 MSPS whilst keeping the board the same size. This would require some re-work of the board and a re-writing of the FPGA code.
We do have a design for a modern Rx board, but have no firmware for this new board as yet. One option would be to either create a hybrid Rx board, or write new firmware for the new board based on the original board’s FPGA code.
