The BCM85021 from Broadcom is a 3G/4G/5G transceiver that operates from 400 MHz to 8.5 GHz. It is optimized for integrated carrier aggregation (CA), digital predistortion (DPD) and crest factor reduction (CFR) that enables 5G radio deployment at the lowest total cost of ownership. Manufactured on an advanced CMOS process, it includes 32 high-speed digital-to-analog RF converters, 32 high-speed analog-to-digital RF converters, eight high-speed analog-to-digital RF observation converters, and the associated digital-processing logic enabling sample decimation, interpolation, filtering and tuning. It connects to the DFE devices using JESD204C and JESD204D SerDes lanes.
The BCM85021 is available in a 780-ball BGA package measuring 35 × 35 mm with a 0.8 mm pitch. It is ideal for use in wireless infrastructure base stations, 5G, LTE, massive MIMO, NB-IoT, mmWave, TDD, and FDD applications.
