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).
