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.
