Shenzhen Mingjiada Electronics Co., Ltd [Supply] TI RF Sampling Transceiver AFE7700IABJ AFE7700 4-Channel Transmit, 4-Channel Receive, 2-Channel Feedback, 600MHz to 6GHz, Four PLLs, General Purpose RF Transceiver

AFE7700IABJ Device Description

The AFE7700IABJ device is a high performance multi-channel transceiver that integrates four direct upconversion transmitter chains, four direct downconversion receiver chains, and two wideband RF sample digitisation auxiliary chains (feedback paths). The high dynamic range of the transmitter and receiver chains enables high-performance wireless transceiver systems. 

The AFE7700IABJ's low power dissipation and large-scale channel integration enable the device to overcome the power and size limitations of multi-antenna and phased array systems. Wideband and high dynamic range feedback paths enable digital pre-distortion (DPD) for power amplifiers and IQ correction in the transmitter chain. The high speed of the serialiser/deserialiser reduces the number of channels required for incoming and outgoing data.
