3 Description

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.
