The AFE7903-x is a high performance, wide bandwidth multi-channel transceiver, integrating two RF sampling TX chains and two RF sampling RX chains. With operation up to 7.4GHz, this device enables direct RF sampling in the HF, VHF, UHF, 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 400MHz of signal bandwidth. 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 RX 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 400MHz for two RX.
