FPGA · RF · REAL-TIME SIGNAL PROCESSING
We develop FPGA firmware and real-time signal processing, and design RF and mixed-signal hardware. Projects range from a single IP core to complete systems including schematics, PCB layout, embedded software and laboratory validation.
For SDR, radar, coherent acquisition and scientific research, our in-house-developed 
VORTARIAN platform → provides a proven hardware, FPGA firmware and software baseline for customer-specific development.
Engineering range
Every figure below comes from hardware and firmware that JSE designed, built and measured, in customer projects and on our own platforms.
Engineering services
From focused FPGA development to complete systems combining real-time signal processing, RF and high-speed electronics.
FPGA architecture, VHDL development, signal-processing implementation, verification, timing closure, optimization and hardware bring-up.

Real-time DSP, algorithm implementation, SDR development, embedded Linux, drivers and high-throughput data paths for FPGA-based systems.
Explore software servicesJSE SDR Development platform
Designed entirely in-house at JSE, our coherent multi-channel SDR platform gives your project a proven hardware, FPGA and software baseline.
Schematics, PCB layout, FPGA firmware and embedded software all come from JSE, so any part of the platform can be adapted to your requirements.
Coherent RF acquisition and generation, high-speed ADC/DAC conversion, FPGA signal processing, RISC-V with embedded Linux and dual 10 GbE.
Customer-specific hardware, FPGA and software development starts from measured, working hardware instead of a blank page.
Optional RF mezzanine front-ends extend coverage up to 75 GHz, and multiple boards can be synchronized for coherent operation.

Measurements and engineering notes from our RF, FPGA and SDR work.
A port-by-port guide to the VORTARIAN 4R2T-10G board: four coherent RF inputs, two RF outputs, a shared 100 MHz reference, trigger I/O and two 10 GbE links for low-latency communication, radar and SDR receivers.
Network cards, switches, SFP+ modules and cables tested with the VORTARIAN 4R2T-10G in long-term streaming runs without UDP packet loss.
JSE is now listed as a design services partner in the Altera partner directory.
Phase noise of the 500 MHz ADC sampling clock on the VORTARIAN SDR platform: 30.4 fs RMS from 1 kHz to 10 MHz. Why phase noise matters, why jitter depends on the integration range, and which range fits radar and communications.
