SBASAO5A april 2023 – june 2023 AFE7901
PRODUCTION DATA
The AFE7901 is a high performance, wide bandwidth multi-channel transceiver, integrating four RF sampling transmitter chains and four RF sampling receiver chains. With operation up to 7.4 GHz, this device enables direct RF sampling in the L, S and C-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 TX signal paths support interpolation and digital up conversion options that deliver up to 400 MHz of signal bandwidth per TX path using a single or dual digital up converter. 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.
