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.
