High-Speed High-Fidelity Reprogrammable Kernel for DRFM Applications

A four channel DRFM module integrated the GHz ADC and DAC with Xilinx Vertex6 FPGA on the PCB is proposed. All the components will use proven commercial off-the-self (COTS) products to minimize technical risks. The converters will be selected based on the bandwidth, broadband SFDR, latencies and synchronization capabilities. DSP core is propsoed with polyphase channelized receiver and transmitter for single signal path.The basic amplitude, phase and frequency modulations will be implemneted with frequency resolution better than 0.1 Hz. Three types of memories will be used to meet the delay and data size requirements. There will be four signal paths for a complete DRFM kernel. This DRFM module leverages the core technologies of Euvis'existing module products such as Multi-Gsps AWGs, 2 Gsps digitzers and FPGA codes. The developed DRFM will provide 500 MHz instantaeous bandwidth with 60 dB SFDR.
