MIMO Linearizer Paves the Way for Greener Network Deployments

SAN JOSE, Calif., May 17, 2016 /PRNewswire/ -- Designers can now achieve lower power, cost, and size of the RF front-end with the SC2200 dual-channel RF power amplifier linearizer (RFPAL) from Maxim Integrated Products, Inc. (NASDAQ: MXIM).

The linearizer enables power amplifiers to consume up to 70% less power compared to operation in back-off. In addition, it reduces the bill of materials (BOM) cost by up to 50%, and is up to 8x smaller than other digital pre-distortion (DPD) solutions on the market. The SC2200 application, which occupies less than 1 square inch of board space, substantially increases power amplifier efficiency while consuming less than 1.5W when both paths are fully operational. This allows manufacturers to realize significant competitive advantages and helps operators meet their requirements for lowered operating and deployment costs.

With cellular data traffic increasing exponentially, the communications industry is migrating from voice-centric macro networks to heterogeneous networks with improved coverage and capacity. The SC2200 is a superior alternative to the inefficient method of operating power amplifiers in back-off, and is preferred over DPD since it requires no software or complex algorithm development. It features an integrated pre-amp and a single 1.8V supply, and works optimally for a wide range of power amplifier architectures, technologies, and power levels. The linearizer is suitable for 2G, 3G, and 4G systems, including TD-LTE and FD-LTE. It is ideal for cellular infrastructure applications such as macro and small cell base stations, distributed antenna systems (DAS), active antenna systems (AAS), remote radio heads, and other multiple-input multiple-output (MIMO) systems.

Commentary

• "The SC2200, based on field-proven RFPAL technology that has been deployed in millions of base stations, is already being used in early stage 5G systems utilizing massive MIMO antenna arrays," said Elina Todorov, Business Manager at Maxim Integrated. "The SC2200 provides higher integration and functionality over previous generations, enabling base station vendors to substantially reduce system costs."
