AFE7700
SLOSE44A –OCTOBER 2019–REVISED MARCH 2020
AFE7700 Quad-Channel General Purpose RF Transceiver
1 Features
3 Description
The AFE7700 device is
a
high-performance,
1
•
•
•
Quad transmitters based on direct up-conversion
architecture:
multichannel transceiver, integrating four direct up-
conversion transmitter chains, four direct down-
conversion receiver chains, and two wideband RF
sampling digitizing auxiliary chains (feedback paths).
The high dynamic range of the transmitter and
receiver chains enables high performance wireless
transceiver systems.
–
Up to 600 MHz of RF transmitted bandwidth
per chain
Quad receivers based on 0-IF down-conversion
architecture:
–
Up to 200 MHz of RF received bandwidth per
chain
The low power dissipation and large channel
integration of the AFE7700 allows the device to
address the power and size constraints of multi-
antenna and phased array systems. The wideband
and high dynamic range feedback path can assist the
Digital Pre-Distortion (DPD) of power amplifiers and
IQ correction in the transmitter chain. The fast
SerDes speed can reduce the number of lanes
required to transfer the data in and out.
Feedback chain based on RF sampling ADC:
Up to 600 MHz of RF received bandwidth
