San Jose, CA — June 26, 2012 — Maxim Integrated Products (NASDAQ: MXIM) announced a variety of key HetNet solutions required for next-generation base station equipment. These solutions include single-chip multi-band radio transceivers, broadband gain blocks, direct RF synthesis DACs, and intelligent digital point-of-load (POL) controllers.

Cellular radio access networks (RAN) are evolving into heterogeneous networks (HetNet), which require a diverse range of analog and mixed-signal base station solutions for major radio signal paths, baseband processing support, and power conversion nodes. Maxim anticipated this evolution into HetNet and is providing new, highly integrated solutions featuring high dynamic performance, low power consumption, and high reliability.

HetNet is a coordinated collection of core 3G/4G wireless infrastructure elements that make up macro cells and small cell base stations. All network components work together to provide high data throughput, high mobility, and the exceptional high quality that mobile broadband subscribers can expect from 3G/4G networks. With the rapid increase in mobile media and data consumption, subscribers can experience reliable and seamless connectivity anytime, anywhere through the HetNet architecture.
