36 PRODUCTS Multi-band mobile WiMAX receiver helps accelerate global network deployments Agilent Technologies has introduced a measurement receiver for Mobile WiMAX, extending the technology support of its existing drive test receiver platform. This receiver enables network equipment manufacturers and wireless operators’ RF engineering teams to effectively deploy, optimize and troubleshoot Mobile WiMAX networks by quickly identifying coverage and interference problems. The W1314A platform has options to support GSM, UMTS, IS95, cdma2000, 1xEVDO, iDEN and WiMAX™ technologies. As WiMAX technology matures and more advanced network designs are realized, it is important to maximize the effectiveness of drive-test teams by providing them the ability to quickly and accurately collect Beneﬁts of the Agilent W1314A-E01 receiver include: — the ability to quickly troubleshoot handover and missing-neighbor issues, conﬁrm coverage and pinpoint interference sources; — support of up to eight frequency bands, which allows 2.3, 2.5 and 3.5 GHZ Mobile WiMAX networks to be monitored by a single, compact solution; — small form factor and rugged casing, which makes the solution easy to carry and able to withstand the rough environment of ﬁeldbased testing; — and a builtin high sensitivity GPS that offers signiﬁcantly enhanced position-reporting performance in dense urban environments as well as in many indoor situations. www.mwee.com/206801257 RF measurement data. This latest receiver integrates with the industry-leading Agilent E6474A network optimization software to provide a core of RF coverage data, technologyspeciﬁc interference and optimization measurements. “As Mobile WiMAX begins to compete head on with other 3G and 3.5G technologies, there is even greater need to validate the network design and performance targets as quickly as possible,” said Jonathan Dunbar, general manager of Agilent’s Drive Test business.” “Unlike a standard Mobile WiMAX subscriber device, the network independent receiver measurements enable users to clearly see individual sector coverage areas and validate that they meet the design criteria.” Programmable CMOS RF transceiver spans 700 MHz to 3.8 GHz BitWave Semiconductor reports that it has launched the world’s ﬁrst programmable CMOS RF transceiver. Known as the BW1102 Softransceiver RFIC, the device is software conﬁgurable across all channels in the frequency bands between 700 MHz and 3.8 GHz, with bandwidths of 25 kHz to 20 MHz. This means that the BW1102 can be conﬁgured for multiple wireless protocols such as GSM, GPRS, EDGE, WCDMA, HSDPA, CDMA2K, EVDO, 802.11b/g and 802.16d/e. Optimized for low cost and low power, the BW1102 is well suited for use in the cellular handset and femtocell markets. Responding to the need for global connectivity, BitWave designers developed the BW1102 RFIC to enable wireless consumer applications to seamlessly switch between multiple frequency bands and wireless communication protocols. Beneﬁts of using the BW1102 in wireless designs include: reduced component counts, BOM costs, and time to market. BitWave reports that the ﬂexibility of multiple wireless bands and multiple protocols of operation is achieved using software mode ﬁles, a ﬁrst in the RFIC industry. The BW1102 is built on a standard digital CMOS process and is supplied in a 7 x 7 mm PBGA package for low cost and small size. The transceiver includes built-in test and calibration. Samples of the BW1102 will begin shipping during the next month and volume production shipments will begin during Q3 2008. www.mwee.com/206801251 Broadcom unveils 65-nm mobile TV receivers support both DVB-T and DVB-H for the handset market Broadcom’s 65-nm digital TV single-chip receivers support the DVB-T (Digital Video Broadcast-Terrestrial) and DVB-H (Digital Video Broadcast-Handheld) standards. The BCM2940 integrates a dual-mode demodulator and tuner to support both DVB-T and DVB-H for the high-growth cellular handset market. The BCM2930 is optimized for DVB-T applications targeting settop-box and PC markets, and enables digital TV broadcasts as a value-added feature on portable platforms. An aggressive process technology implementation means the BCM2940 and BCM2930 significantly reduce power consumption by up to 40 percent and footprint requirements by up to 30 percent from current handset design budgets. Advanced tuner and demodulator design of both chips allows for measurably improved reception indoors and in high-speed environments. The BCM2940 and BCM2930 receivers integrate state-of-the-art RF tuners with standards-compliant DVB-T and DVB-H digital basebands on single die. They support the VHF III, UHF IV and V bands. The BCM2940 additionally supports the EU/US L-bands and integrates 4Mb MPE-FEC SRAM to handle DVB-H parallel/consecutive streams and services. Both offer a variety of physical interfaces including SPI, SDIO and USB 2.0. Both are available in an FBGA package while the BCM2940 is also available in a WLBGA package www.mwee.com/206801305 Microwave Engineering Europe ● March 2008 ● www.mwee.com 036_MWEE.indd Sec1:36 22/02/08 16:38:42 http://www.mwee.com/206801257 http://www.mwee.com/206801251 http://www.mwee.com/206801305 http://www.mwee.com
