LBRX-24 L-Band/IF Channelizing Digitizer

The LBRX-24 receiver system employs FlexRadio Systems’ SDR technology to simultaneously capture, digitize and stream up to 24 channels of wideband satellite or terrestrial IF signals in the 950 to 2150 MHz frequency range. Each of the 24 independent receiver/digitizers allows for selectable tuning frequencies, bandwidth, and sampling rates for maximum system flexibility. Streaming of output data of up to 80 MHz bandwidth per channel is accomplished via 4 x 10Gb Ethernet ports using the industry standard VITA-49 or SDDS communications protocols.
