XRONet Samples Mobile WiMAX Chipset Touting Low Power Consumption and Small Footprint

XRONet corporation of Korea announced that it is sampling a chipset of Baseband MAC/PHY SoC (XRO7000) and RF Transceiver IC (XRO3000), targeting Mobile WiMAX Wave2/Wave1/WiBro terminals. XRO7000 and XRO3000 support all features of Mobile WiMAX Wave2 profile, and well exceed the performance requirements. With its unprecedented low power consumption and small form factor, the chipset is a perfect solution for handheld devices like smartphones, PDAs, mobile internet devices, UMPCs (Ultra mobile PCs), as well as USB dongles, PC cards, express cards, SDIO devices.

According to XRONet, the highly integrated Baseband and RF chipset raises the bar on the performance to power ratio of Mobile WiMAX chipset in the market. The chipset puts together all the features covering, Mobile WiMAX Wave2 as well as Wave1 and WiBro (the World’s first commercial Mobile WiMAX service in Korea) in a single chip baseband SoC and a single chip RF IC. XRONet’s hardwired 2×2 MIMO OFDMA engine provides spatial multiplexing doubling the data rate, and Space time coding, doubling the cell range. Its MIMO algorithm gives the ML (Maximum likelihood) performance, the theoretical limit of Spatial multiplexing at the fraction of power consumption of conventional ML algorithms. The chipset’s optional 2 Transmitters can boost the capacity of uplink as well. XRO7000’s unique distributed architecture with hardwired PHY and MAC engines, on-chip AD/DA, low power CPUs, and memories, and its dynamic power manager, minimize the chipset’s power consumption on the fly. XRO3000’s MIMO-optimized direct conversion RF architecture raises the performance limit in TX/RX EVM, noise figure, phase noise, linear TX power, and dynamic range.

XRO7000 is a single chip Modem SoC that suppots PUSC, FUSC, Band-AMC, 2×2 MIMO SM/STBC for Both Downlink/Uplink, Collaborative SM, Channel Sounding for Beamforming, HARQ, CC, CTC, ARQ, QoS, IPv4/v6, PKMv2, UICC, EAP/AKA, Sleep/Idle, and HO optimization. XRO7000 provides a variety of host interfaces including Notebook PC, PDA, Smartphone, Portable Media Player, portable game console, Car Navigation systems, etc.

XRO3000 is a single chip RF Transceiver IC integrating a PLL, LNAs, Mixers, VGAs, Drive Amp, Low pass filters, and auto-calibration of DC/IQ offset, and multiple chains for MIMO. It supports multi-bands from 2.3GHz to 2.7GHz (3.5GHz support coming soon) with multiple channel bandwidths from 3.5MHz to 10MHz.

XRO7000 and XRO3000 come with a complete software suite of MAC, device drivers, connection manager, RF calibration software, and a reference design kit. A baseband-RF single chip solution is expected to sample in Q1 ’08.
