Description for the AFE8030
The AFE8030 is a high performance, wide bandwidth multichannel 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 AFE8030 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 single or dual digital down converter (DDC) provides up to 600MHz of combined signal BW. 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.
The feedback path includes a 25dB range DSA driving a 3GSPS RF sampling ADC, followed by a single wide DDC or two narrower DDCs with up to combined 800MHz bandwidth (1200MHz in 4-channel mode).
