PRODUCTS 41 High linearity VCO operates over 902 to 928 MHz Crystek’s CVCO55CL-09020928 VCO operates from 902 MHz to 928 MHz with a control voltage range of 0.5 V to 4.5 V. This VCO features a typical phase noise of 115 dBc/Hz at 10 kHz offset and offers excellent linearity. Packaged in the industry standard 0.5- x 0.5-inch (1.27 x 1.27 mm) SMD package, the VCO has an input voltage of 5.0 V, with a maximum current consumption of 20 mA. Pulling and Pushing are minimized to 2.00 MHz and 0.80 MHz/V, respectively. Antenna tuning switch delivers industry-leading linearity and IMD performance Peregrine Semiconductor has unveiled the UltraCMOS™ PE42641 SP4T antenna tuning switch delivering an unparalleled IMD performance of -110 dBm, making it ideal for converged designs requiring high linearity and low distortion. A variety of emerging market applications benefit from the RF performance advantages of the PE42641 switch, including 3G GSM/EDGE/WCDMA and CDMA handset and PC card applications; machine-tomachine applications such as vending machines and parking meters; or designs requiring antenna tuning, such as repeater and telematics applications. The UltraCMOS siliconon-sapphire based PE42641 incorporates Peregrine’s HaRP™ technology enhancements to deliver industry leading harmonic results, linearity and overall RF performance: high linearity of +68 dBm IP3 or -110 dBm IMD; harmonics better than -80 dBc, low insertion loss of 0.5 dB (typical); high isolation 35 dB at critical paths; and complete monolithic integration. Additionally, the Second harmonic suppression is typically -15 dBc. Typical applications include digital radio equipment, fixed wireless access, satellite communications systems, and base stations. www.mwee.com/206800062 Embedded module series models for HSPA and EV-DO Revision A networks Sierra Wireless has announced two embedded modules — the MC8785V for HSPA networks, and the MC5727 for EV-DO Revision A networks. MC8785V is voice-enabled and offers a peak data speed of up to 7.2-Mbits/s on the downlink and 2.0-Mbits/s on the uplink (upgradeable to 5.76-Mbits/s). The module offers tri-band HSPA/UMTS support with receive diversity on all three frequency bands, as well as quad-band support for EDGE/GPRS/GSM. Globally compatible, the module enables OEMs to concentrate on a single product for use in all markets. Voice enabled capability makes the MC8785V wellsuited for ﬁxed wireless terminals and portable handheld devices that require the ability to make voice calls. The MC5727 embedded module includes the latest in EV-DO Revision A technology and supports upcoming feature enhancements, enabling OEM customers to futureproof devices currently in development for EV-DO Rev A networks. It offers peak data speeds up to 3.1-Mbits/s on the downlink and up to 1.8 Mbits/s on the uplink. www.mwee.com/206104895 new switch offers Class 2 ESD (2 kV HBM) on all pins, and Class 3 (4 kV HBM) at the antenna, which is the highest ANT-pin ESD protection available today. With the UltraCMOS PE42641, the industry is finally able to deliver on the promise of tuning capability in mobile devices, a challenge which has been on the whiteboards of antenna designers for many years. PE42641 is Peregrine’s first step in supporting the emerging market of tunable components. Further, as with the company’s entire portfolio, this SP4T is developed on UltraCMOS which is a standard CMOS technology. It leverages all the same low-cost, high-value benefits in manufacturing yields, scalability and easeof-use, while delivering the unprecedented performance offered only with our proprietary sapphire substrate. www.mwee.com/206801232 SoC brings location-based services to mobile devices ensures high performance with minimal impact to battery life RF Micro Devices has announced the introduction of the RF8000 series of location solutions for global positioning system (GPS) applications. The highly integrated, low power RF8000 series of location solutions features softwarebased, system-on-chip (SoC) architectures and is designed speciﬁcally for energy-sensitive mobile devices enabling location-based services. Mobile device manufacturers using the RF8000 series to enable location-based services will enjoy the beneﬁts of a powerful processing engine implemented in a highly integrated, low power platform. The RF8000 architecture features an efﬁcient RF design, ﬂexible virtual correlation algorithms, powerful accelerator engine and innovative signal processing techniques, all delivered in a compact SoC format. The efﬁcient architecture accommodates the stringent power requirements of cellular handsets, and the reduced solution size and minimal external component count are sensitive to the limited area available for complementary radios in mobile devices. The RF8000 series claims to set a new standard of performance per square millimeter with minimal impact to battery life. www.mwee.com/206801247 Microwave Engineering ● March 2008 ● www.mwee.com 041_MWEE.indd Sec1:41 22/02/08 15:09:04 http://www.mwee.com/206800062 http://www.mwee.com/206104895 http://www.mwee.com/206801232 http://www.mwee.com/206801247 http://www.mwee.com
