The AFE7922 is a high performance, wide bandwidth multichannel transceiver, integrating two RF sampling transmitter chains and two RF sampling receiver chains. The high dynamic range of the transmitter and receiver chains allows the device to generate and receive 3G, 4G, and 5G signals from wireless base stations, while the wide bandwidth capability of the AFE7922 is designed for multiband 4G and 5G base stations.

The TX signal paths support interpolation and digital up conversion options that deliver up to 400MHz of signal bandwidth per TX channel. The output of the DUCs drives a 12GSPS DAC (digital to analog converter) with a mixed mode output option to enhance 2nd Nyquist operation. The DAC output includes a variable gain amplifier (TX DSA) with 40dB range and 1dB analog and 0.125dB digital steps.

Each receiver chain includes a 25dB range DSA (Digital Step Attenuator), followed by a 3GSPS ADC (analog-to-digital converter). Each receiver channel has an analog peak power detector and various digital power detectors to assist an external or internal autonomous automatic gain controller, and RF overload detectors for device reliability protection. Flexible decimation options provide optimization of signal bandwidth of up to 400MHz per RX channel.

AFE7920EVM — AFE7920 四发射四接收、双反馈路径射频采样收发器评估模块

AFE7920 评估模块 (EVM) 是一个射频采样收发器平台，通过配置可同时支持最多四个发射、四个接收和两个反馈 (4T4R+2FB) 通道。

此电路板可评估 AFE7920 器件，这是一款四通道射频采样模拟前端 (AFE)，具有 14 位 12GSPS 数模转换器 (DAC)、14 位 3GSPS 模数转换器 (ADC) 以及为 DAC 和 ADC 生成高频时钟的片上集成锁相环 (PLL) 和压控振荡器 (VCO)。

AFE7920EVM 可在每个通道使用双频带数字升压转换器和降压转换器，从而同时将具有高动态范围的多个宽带信号合成并实现数字化。接收通道支持片上集成数字步进衰减器 (...)
