The AFE7900-x is a high performance, wide bandwidth multi-channel transceiver, integrating four RF sampling TX chains, four RF sampling RX chains and two RF sampling FB chains (six RF sampling ADCs total). With operation up to 7.4GHz, 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 1200MHz of signal bandwidth for four TX or 2400MHz for two TX. The output of the DUCs drives a 12GSPS DAC with a mixed mode output option to enhance 2nd Nyquist operation. The DAC output includes a variable gain amplifier (TX DSA) with 40dB range and 1dB analog and 0.125dB digital steps.

Each receiver chain includes a 25dB range DSA (Digital Step Attenuator), followed by a 3GSPS ADC. Each receiver channel has an analog peak power detector and various digital power detectors to assist an external or internal autonomous automatic gain controller, and RF overload detectors for device reliability protection. Flexible decimation options provide optimization of data bandwidth up to 1200MHz for four RX without FB paths or 600MHz with two FB paths (1200MHz IBW per FB ADC).
