Maxim's analog integration capabilities focus on support of the evolving HetNet

June 26, 2012 // By Paul Buckley
Maxim Integrated Products, Inc. has unveiled several essential HetNet solutions needed for next-generation base-station equipment. The solutions include single-chip multiband radio transceivers, broadband gain blocks, direct RF synthesis DACs, and intelligent, digital, point-of-load controllers. 

The cellular radio access network (RAN) is evolving to a heterogeneous network that demands a set of diverse analog and mixed-signal base-station solutions required for the main radio signal paths, baseband processing support, and power-conversion nodes. Maxim has anticipated the HetNet evolution and is offering new solutions that deliver dense analog integration with high dynamic performance, low power, and high reliability.     

HetNet is the coordinated deployment of critical 3G/4G wireless infrastructure elements comprising macro cell and small cell base stations, residential femto cells, and mobile backhaul. The network elements work in concert to deliver the high data throughput, high mobility, and the exceptional quality of experience that mobile broadband subscribers expect from the 3G/4G network. With exploding mobile media and data consumption patterns, subscribers will experience reliable, and seamless connectivity from the HetNet architecture.     

Maxim's MAX2550–MAX2553 single-chip small-cell radio transceivers improve residential coverage and network capacity.     

The company's MAX5879 direct RF synthesis DAC for multicarrier, multiband, and multistandard macro cell, small cell, and wireless backhaul transmitters; allows designers to develop a fully digital RF transmitter on a common hardware platform.     

The MAX2870 ultra-wideband 23.5 MHz to 6000 MHz synthesizer with integrated VCO enables multiband LO frequency synthesis in base-station radios.     

MAX15301 InTune digital point-of-load controller with automatic compensation, integrated FET driver, and integrated PMBus telemetry delivers high-efficiency, intelligent, power-management nodes to radio and baseband units.     

The MAX2612–MAX2616 broadband, 40 MHz to 4000 MHz gain blocks deliver exceptional gain flatness, noise figure, and linearity; ideal for general-purpose RF amplifier applications in base-station and wireless backhaul radios.
