3 Description
The AFE7700 device is a high-performance,
multichannel transceiver, integrating four direct upconversion
transmitter chains, four direct downconversion
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.
The low power dissipation and large channel
integration of the AFE7700 allows the device to
address the power and size constraints of multiantenna
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.
