3 Description

The AFE8192 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 AFE8192 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 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.
