Description

The AFE8092 is a high performance, wide bandwidth multi-channel transceiver, integrating eight RF sampling transmitter chains, eight RF sampling receiver chains and two separate RF front end for the auxiliary chains (feedback paths). The high dynamic range of the transmitter and receiver chains allows generating and receiving 3G, 4G and 5G signals for wireless base stations, and the AFE8092 wide bandwidth capability is designed for multi-band 4G and 5G base stations. Each receiver chain includes a 31dB range DSA (Digital Step Attenuator), followed by a 3GSPS ADC (analog-to-digital converter). Each receiver channel has analog peak power detectors and digital peak and power detectors to assist an external or internal autonomous automatic gain controller, and RF overload detectors for device reliability protection. The digital down converters (DDC) provides up to 800MHz of combined signal BW in 8-channel mode and 800MHz in 4-channel mode. In TDD mode, the receiver channel can be configured to dynamically switching between traffic receiver (TDD RX) and wideband feedback receiver (TDD FB), with the capability of re-using the same analog input for both purposes. Each transmitter chain includes a digital up converter (DUC) supporting up to 800MHz combined signal bandwidth (1200MHz in 4-channel mode). The output of the DUC 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. The feedback path includes a 25dB range DSA driving a 3GSPS RF sampling ADC, shared with receiver chain, followed by a DDC with up to 800MHz bandwidth (1200MHz in 4-channel mode).
