The AFE7955 is a high performance, wide bandwidth multi-channel transceiver, integrating two RF sampling transmitter chains and 3 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 1200 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.

Two receiver chains includes a 25-dB range DSA (Digital Step Attenuator), followed by a 3-GSPS ADC (analog-to-digital converter). The two receiver channels have 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 signal bandwidth of up to 1200 MHz per RX channel.

An additional receiver channel has a single wideband DDC supporting up to 1200 MHz bandwidth.
