Four-channel 7.4GHz RF-sampling transceiver with 6GSPS receive (RX) and 12GSPS transmit (TX)

The AFE810x is a high

performance, wide bandwidth multi-channels transceiver, integrating eight (AFE8108)/ four

(AFE8104) RF sampling transmitter chains and eight (AFE8108)/ four (AFE8104) RF sampling

receiver chains.

Each receiver chain includes a 6GSPS ADC

(analog-to-digital converter), two digital peak detectors to assist an external autonomous

automatic gain controller and RF overload detectors for device reliability protection. The

single digital down converters (DDC) provides up to 800MHz of signal BW in 8 channels mode,

1600MHz in 4 channels and up to 2400MHz in 2 channels mode.

Each transmitter chain includes a digital up

converters (DUCs) supporting up to 800MHz (8T), 1600MHz (4T) or 2400MHz (2T) of signal

bandwidth. The output of the DUCs drives a 12GSPS DAC (digital to analog converter) with a

mixed mode output option to enhance 2nd Nyquist operation.
