The AFE7769 is a Quad-channel RF transceiver that operates from 600 MHz to 6 GHz. This multichannel transceiver integrates four direct up-conversion transmitter chains, four direct down-conversion receiver chains, and two wideband RF sampling digitizing auxiliary chains (feedback paths).

Each receiver chain includes a 28-dB range digital step attenuator (DSA), followed by a wideband passive IQ demodulator, and a baseband amplifier with integrated programmable antialiasing low pass filters, driving a continuous-time sigma-delta ADC. The RX chain can receive an instantaneous bandwidth (IBW) up to 200 MHz.

Each transmitter chain includes two 14-bit, 3-Gsps IQ DACs, followed by a programmable reconstruction and DAC image rejection filter, an IQ modulator driving a wideband RF amplifier with 39-dB range gain control.

The low power dissipation and large channel integration of this transceiver allows the device to address the power and size constraints of 4G and 5G massive MIMO base stations. The wideband and high dynamic range feedback path can assist the Digital Pre-Distortion (DPD) of the power amplifiers in the transmitter chain. The fast SerDes speed can help reduce the number of lanes required to transfer the data in and out.

The synthesizer section integrates four fractional-N RF PLL that can generate four different RF LO, allowing the device to support up to two different bands, each one configured as two transmitters, two receivers and one feedback paths. It is available in a 17 x 17 mm FCBGA package and is ideal for small cell base station, distributed antenna system (DAS), active antenna system mMIMO (AAS) and repeater applications.
