DesignArt Networks has formally launched its 40nm 4G SoC family, starting with the release of five SoCs. The company has also introduced DAN3400, its second open SoC platform.

Tapping the vast baseband processing resources of the DAN3000 SoC family architecture, DAN3400 was designed for simultaneous multiprotocol operation in a distributed multigigabit radio access network (RAN). DAN3400 is the only available single-SoC solution for the design of fully integrated high-performance, multiprotocol base station and relay equipmentideal for the small cell layer of the heterogeneous mobile network.

"At the heart of DAN3400 is the most scalable multiprotocol baseband pipeline, consisting of optimized multicore DSP and RISC processing layers, and augmented with software-programmable hardware acceleration for the simultaneous operation of high-capacity W-CDMA and LTE micro- and picocells, in-field software-upgradable to 4G LTE Advanced," said Assaf Touboul, DesignArt Networks chief technology officer. "Consuming less than 6W, the DAN3400 SoC platform delivers a truly carrier-grade small cell solution, suitable for the design of ultra-compact, low-cost single-SoC Micro- or Pico BTS equipment with flexible RF output power."

DAN3400 combines all base station processing layers with a powerful SW-programmable digital RF front-end (DFE)enabling the most integrated single-SoC base station designs. The embedded DFE, with high-efficiency PA linearization, drives a multicarrier, multiprotocol 4x4 antenna array with a combined channel width of up to 40MHzfully ready for LTE Advanced features such as spectrum aggregation, MU-MIMO and high-performance LTE relay.

Single-SoC compact base station equipment based on DAN3400 provides multiprotocol access to multiple spectrum assets of operators with in-field software upgrade to a multicarrier 40MHz 4G picocelldelivering aggregated 600Mbit/s of 4G mobile broadband data capacity.
