The AFE8190 is a high performance, wide bandwidth multi-channels transceiver, integrating sixteen RF sampling transmitter chains, sixteen RF sampling receiver chains and four separate RF sampling auxiliary chains (feedback paths). The high dynamic range of the transmitter and receiver chains allows generating and receiving 3G, 4G and 5G signals for wireless base stations, while the wide bandwidth capability makes the AFE8190 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 5GSPS 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 single digital down converters (DDC) provides up to 600MHz of signal BW.
Each transmitter chain includes a digital up converters (DUCs) supporting up to 800MHz 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. The DAC output includes a variable gain amplifier (TX DSA) with 39dB range and 1dB analog and 0.125dB digital steps.
