Description
General part information
AFE7769 Series
The AFE7769 device is a high-performance, 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 wireless base stations to generate and receive 2G, 3G, 4G, and 5G signals.
The low power dissipation and large channel integration of the AFE7769 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.
Each receiver chain of the AFE7769 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 receiver channel has two analog peak power detectors and various digital power detectors to assist an external or internal autonomous AGC control for receiver channels, and a RF overload detector for device reliability protection. The integrated QMC (quadrature mismatch compensation) algorithm is capable to continuously monitor and correct for the RX chain I and Q imbalance mismatch without the need to inject any specific signals or perform offline calibration.
