FMC Dual channel L band front-end
Sample text - to be replaced>*
The dual channel L band front-end consist of a FMC dual channel L band
down-converter, preamplifiers and duplex filters.
Each IQ down-converter has a wide adjustable bandwidth (>100 MHz),
adjustable gain and two 250MHz 8 bits or 160 MHZ 12 bits or 105MHZ 14
bits multi-mode ADC’s. The down-converter mode is switchable: single
receiving frequency band for both channels, or dual frequency band: each
channel has its own receiving frequency band. For GNSS its includes
timing support, Other applications are radio astronomy and microwave
digitizing back-end.
The FMC VME Carrier is an FMC carrier that can hold two FMC cards and an SFP connector. The FMC mezzanine slots use low-pin count (LPC) connectors. This board is optimised for cost and will be usable with most of the FMC cards designed within the OHR project (e.g. ADC cards, Fine Delay). For boards needing more possibilities (e.g. programmable clock resources, fast SRAM, fast interconnect between carriers), the VME FMC Carrier - VFC can be used.
