The AD9375 is a highly integrated, wideband RF transceiver that is tunable over a range from 300 MHz to 6 GHz. It has been developed to simplify and accelerate radio development for wireless carriers and telecommunications equipment manufacturers as they transition their cellular base stations from 4G to 5G networks.
This transceiver allows customers to quickly evaluate and develop radio designs for 4G small cell and Pre-5G massive MIMO systems, key building blocks in the transition to 5G, enabling faster data rates while improving connectivity and data throughput in densely populated, high-traffic areas such as office buildings, sport stadiums and public transit systems.
The transceiver integrates dual-channel transmitters (Tx) and receivers (Rx), integrated synthesizers, a fully integrated digital predistortion (DPD) actuator and adaptation engine, and digital signal processing functions. It has two 100-MHz receivers, two 250-MHz transmitters, a two-input observation receivers and a three-input sniffer receivers.
The integrated digital pre-distortion (DPD) solution supports 3G and 4G waveforms with an instantaneous signal bandwidth of up to 40 MHz. The IC supports Rx bandwidths up to 100 MHz. It also supports observation receiver (ORx) and Tx synthesis bandwidths up to 250 MHz to accommodate digital correction algorithms. It operates on a 6-Gbps JESD204B interface supporting lane rates up to 6144 Mbps and consumes less than 5 Watts of power. A 1.3 V supply is required to power the AD9375 core, and a standard 4-wire serial port controls it. The AD9375 is available in a 12 mm x 12 mm, 196-ball chip scale ball grid array and is ideal for 3G/4G small cell base stations and 3G/4G massive MIMO/active antenna systems.
