The AFE8152 is
a high performance, wide bandwidth, and multichannel transceiver with sixteen integrated 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 for generating and receiving 3G, 4G, and 5G signals for wireless base
stations, while the wide bandwidth capability makes the AFE8152
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 single digital down converters (DDC)
provides up to 600MHz of signal BW in 16-channel mode and 1200MHz in 8-channel mode.
Each transmitter chain includes a digital up
converter (DUC), supporting up to 1200MHz of signal bandwidth (1600MHz in 8-channel mode).
The output of the DUC drives a 10GSPS 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.
