Description

The AFE7953 is a high performance, wide bandwidth multi-channel transceiver, integrating two RF sampling transmitter chains and two RF sampling receiver chains. 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 TX signal paths support interpolation and digital up conversion options that deliver up to 400 MHz of signal bandwidth per TX channel. The output of the DUCs drives a 12-GSPS DAC (digital to analog converter) with a mixed mode output option to enhance 2 nd 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.
