Double data rate (DDR) radio frequency (RF) digitization module for software-defined radio (SDR)

A double data rate (DDR) RF digitization module for a software defined radio (SDR) is disclosed. In embodiments, the DDR RF digitization module includes a printed circuit board (PCB) terminating in a DDR memory bus interface comprising a plurality of input/output (I/O) connectors insertable into a DDR slot of an SDR motherboard. The RF digitization module is connectable to an RF front end of the SDR via receiver-side (Rx) and transmitter-side (Tx) RF connectors. The RF digitization module includes DDR analog-digital converters (ADC) and digital-analog converters (DAC) mounted to the PCB and in communication with the RF front end and the DDR memory bus. The DDR ADCs provide high speed digital sampling of inbound RF signals for the signal processors via the DDR memory bus, and the DDR DACs provide high speed generation of transmittable analog RF signals based on digital spectrum data generated by the signal processors.
