Software radio and A/D products are supported by Pentek’s ReadyFlow Board Support Packages.

FPGA-equipped products are supported by Pentek’s GateFlow FPGA Design Kits and the GateFlow FPGA factory-installed IP cores.

Software Defined Radio Handbook
Written by Rodger Hosking, Vice President and Co-founder of Pentek

SDR has revolutionized electronic systems for a variety of applications including communications, data acquisition and signal processing. This handbook shows how DDCs (Digital Downconverters) and DUCs (Digital Upconverters), the fundamental building blocks of SDR, can replace conventional analog receiver designs, offering significant benefits in performance, density and cost.

The inner workings of the SDR are explored with an in-depth description of the internal structure and the devices used. Actual board- and system-level implementations and available off-the-shelf SDR products for embedded systems are described.
