D.&P. has signed an innovative acquisition solution to receive RF signal directly: ADC input bandwidth is extended using an external Track and Hold, obtaining high electrical performance (SFDR of about 50 dBc and SNR of about 40 dB up to 10 GHz in differential input mode).
The HS ADC FMC is a FMC daughter card with an only input channel. Differential and Single-Ended Input modes are available: the former has a wider bandwidth than the latter.
A 2.5 GHz clock allows to have a 1.25 GHz of Instantaneous Input Bandwidth; the sampling clock can be direct or generate through a PLL+VCO using an external reference clock.

The HS ADC FMC Board is mechanically and electrically compliant to FMC standard (ANSI/VITA 57.1).
The board has an high-pin count connector and front panel I/O and it can be used in a conduction cooled environment.
The analog signals are AC coupled and in the front panel there are a few SSMC connectors for external connection.

Application:

Direct RF Down Conversion.
Software defined radio (SDR).
RADAR/SONAR.
Aerospace and test instrumentation.
