The AFE812x is a high performance, wide bandwidth multi-channel transceiver, integrating eight (AFE8128) / four (AFE8124) RF sampling transmitter chains, eight (AFE8128) / four (AFE8124) RF sampling receiver chains and two separate RF sampling auxiliary chains (feedback paths). The high dynamic range of the transmitter and receiver chains allows generating and receiving 2G, 3G, 4G and 5G signals for wireless base stations, while the wide bandwidth capability makes the AFE812x an excellent choice for multi-band 4G and 5G base stations.
Each receiver chain includes a 30dB range DSA (Digital Step Attenuator), followed by a 6GSPS ADC (analog-to-digital converter). Each receiver channel has analog peak power detectors and digital peak and power detectors to assist an external or internal autonomous automatic gain controller, and RF overload detectors for device reliability protection. The digital down converters (DDC) provides up to 800MHz of combined signal BW .
Each transmitter chain includes digital up converters (DUCs) supporting up to 800MHz combined signal bandwidth with a mixed mode output option to enhance 2nd Nyquist operation. The DAC output includes a variable gain amplifier (TX DSA) with 39dB range and 1dB analog and 0.125dB digital steps.
