Transceivers

Transceivers are ready-to-use units comprising transmit and receive functions between LANs over radio-frequency links (satellite, wireless, cable).
Burst-mode or continuous-mode of operation is supported, depending on the model. Likewise, various modulation schemes are available: PSK, spread-spectrum and continuous-phase modulations. Ancillary functions such as error correction and IP network interface are included. The underlying FPGA VHDL source code (not necessary to operate) embodied in these modems is also available for purchase.

Modules

ComBlock modules are small ready-to-use commercial off-the-shelf modules, which are configured with essential communication processing functions, including modulation, demodulation, error correction encoding and decoding, digital to analog/RF, RF/analog to digital, formatting, data storage, networking and high-speed baseband interfaces. ComBlocks are ideally suited for Software Defined Radios.
All FPGA-based modules are pre-programmed with ComBlock IP cores. Source code (not necessary to operate) can also be purchased separately.
