The AFE7954 is a high performance, wide bandwidth quad channel RF sampling DAC. With operation up to 12 GHz, this device enables direct RF sampling in the L, S, C and X-band frequency ranges without the need for additional frequency conversions stages. This improvement in density and flexibility enables high-channel-count, multi-mission systems.
The signal paths support interpolation and digital up conversion options that deliver up to 1200 MHz of signal bandwidth for four DACs (TX) or 2400 MHz for two DACs. The output of the DUCs drives a 12-GSPS DAC (digital to analog converter) with a mixed mode output option to enhance 2nd Nyquist operation. The DAC output includes a variable gain amplifier (TX DSA) with 40-dB range and 1-dB analog and 0.125-dB digital steps.
