40 PRODUCTS Silicon module tuner delivers compatibility with legacy CAN tuners Xceive Corp. has introduced its SiliconNOW module tuner that is positioned to bridge the gap between legacy CAN tuners and silicon-based TV tuners. The SN5000 module tuner features Xceive’s XC5000 silicon tuner and delivers silicon sensitivity, features and functionality optimized for flat panel television screens. Featuring plug-andplay physical compatibility with specific CAN tuners, the SN5000 module tuner offers all the benefits of the XC5000 silicon tuner to TV manufacturers that continue to use the CAN module architecture. In addition, with the XC5000, the SN5000 is said to offer consistent, tight operating variances over millions of units to help minimize cause for recalls. Featuring an integrated programmable DSP to optimize hardware, the SN5000 is configured to meet all television standard requirements, regardless of the geographic location and exceeds the requirements of ATSC, OpenCable, DVBT/ C/H, DMB-TH and ISDBT standards. A two-in-one can replacement supporting onboard demodulation of NTSC, PAL and SECAM TV standards, the SN5000 measures 50 x 27 mm while maintaining a physical footprint to provide compatibility with existing CAN architecture TV design. The SN5000 also incorporates Xceive’s QuickTune technology, which results in ultra-fast per channel signal detection and a complete channel scan of more than 100 channels in less than five seconds. Another feature includes ChannelVista, Xceive’s advanced picturein-picture (PIP) television technology, which allows the viewer to watch up to 12 video channels simultaneously with a single tuner. The QuickTune RF-tobaseband single integrated circuit (IC) TV tuners provide low power and a smaller form factor for the development of advanced TV and PC-TV applications. The RF-tobaseband analog ICs and digital-TV tuner ICs reduce the need for OEMs to maintain multiple inventories in order to service a global market, said Xceive. www.mwee.com/205907382 RF front ends target WLAN multimedia integrate all functionality between Tx and antenna SiGe Semiconductor, Inc. recently announced two RF front-end modules designed to enable new wireless multimedia services in 802.11 a/b/g/n WLANs. The SE2547A and SE2548A integrate all of the functionality required between the transceiver and the antenna in dual-band WiFi systems. The devices include power amplifiers, filtering, power detector, diversity switch, diplexers and associated matching circuitry in a fully tested module that measures 25 mm2. The SE2547A and SE2548A are well suited for use in portable and consumer applications including minicards for personal computing, and can be used to support emerging 802.11n applications such as video distribution, video streaming and highspeed data.. The front-end modules can be used alone, or in stacked configurations to support multiple stream applications. The SE2548A is equipped with a single antenna port allowing it to be used in 2 stream by 2 antenna configuration. The SE2547A provides two antenna ports, allowing two stream by 3 antenna or two stream by 4 antenna configurations. The SE2547A or SE2548A are optimized to deliver high linearity at industry-leading transmit power levels of +18 dBm in 2.5 GHz and +17 dBm at 5 GHz, with bestin-class ACPR performance. The front-end modules include a transmitter power detector for each band and transmit chain with 20 dB of dynamic range for each transmit chain. All RF ports are matched to 50 Ohms. Each transmit chain has a separate digital enable control pin for transmitter power ramp on/off control to aid in power management. The RF front-end modules provide all matching and tuning and are fully tested. www.mwee.com/205918594 Test platform supports all UMTS bands ideal for equipment in North America, Japan & Europe Anritsu Company has added test functions for W-CDMA mobile terminal UMTS bands XI (1.5 GHz) and III (1.8 GHz) to its ME7873F performance test system. With the expanded test capability, the ME7873F now offers mobile terminal carriers and manufacturers a test platform that supports all UMTS bands for testing the RF performance of user equipment in North America, Japan and Europe. Previously, the ME7873F supported conformance tests of 3G W-CDMA mobile terminals in seven UMTS bands. By adding two more bands, the ME7873F can be conﬁgured as a worldwide W-CDMA test solution. It measures Tx and Rx characteristics, and RRM performance based on the 3GPP TS34.121 standards. The ME7873F has received GCF approval for G3.5 HSDPA/ HSUPA mobile terminals. All measurements can be made with a single customized platform, eliminating the need to switch the connection setup in mid-test, according to Anritsu. Up to four mobile terminals can be tested continuously, and the power supply and serial control line can be switched automatically using a terminal switching unit. Test preparations for multiple units can be completed at one time. www.mwee.com/205918646 RF chip replaces IR in AV control easy integration and rich set of peripherals Zensys has launched ZWaveAV, an RF single-chip series for IR replacement in AV control that offer a rich set of peripherals and easy AV device integration. Z-WaveAV single chips and modules are available in three main variants. The ZM4101 single chip includes all of the required RF coupling and passive components. The ZM4101 measures 8 x 8 mm with a QFN56 form factor that makes it what the company says is the smallest RF SoC module in the industry. The ZW0402av single chip is suited for ultra low cost RF remotes, yet still provides IR support of OEM’s legacy AV devices. The ZW0403av is one of the smallest RF SoCs at 2.5 x 2.5 mm and is designed for use as RF interface in AV devices or as an RF modem in high-end remotes with large graphical displays. www.mwee.com/205907397 Microwave Engineering Europe ● January/February 2008 ● www.mwee.com 040_MWEE.indd 40 25/01/08 17:38:23 http://www.mwee.com/205918594 http://www.mwee.com/205907382 http://www.mwee.com/205907397 http://www.mwee.com/205918646 http://www.mwee.com
