36 PRODUCTS 20 to 38 GHz GaAs MMIC low noise amplifier broadband performance in a QFN plastic package Mimix Broadband has introduced a GaAs MMIC low noise amplifier (LNA) in an RoHS compliant, standard 3- x 3-millimeter QFN plastic package, covering 20 to 38 GHz. This LNA, identified as XL1010-QT, delivers 3 dB noise figure and 17 dB small signal gain and is well suited for multiple receiver applications that require broadband performance with simple bias requirements. The LNA also includes onchip ESD protection structures and DC by-pass capacitors to ease implementation and volume assembly. The company claims that the XL1010-QT is Real-time module for urban RF planning tool delivers rapid deterministic propagation capability Remcom has announced a time-enhancing real-timemodule for their Wireless InSite® software tool — an RF planning tool used for site-specific radio signal propagation prediction using ray tracing methods and the Uniform Theory of Diffraction and the Geometric Theory of Diffraction (UTD/GTD). The real time module provides Wireless InSite with a very rapid deterministic propagation capability for urban environments. The module produces higher fidelity results than empirical techniques but at greatly reduced computation times compared to full physicsbased models. Given the location of a transmitter and receiver, the real time module determines the relevant geometry between them and performs a rapid computation of path loss. Loss results are returned in milliseconds, depending on the propagation model, the size and complexity of the urban environment, and the locations of the transmitter and receiver. These almost instant computation times allow for coverage of large areas, or for near-real-time simulations of transmitter and receiver networks. The real time module also allows user-defined objects to be placed into the urban “scene” and their effects on the electromagnetic environment subsequently integrated into the propagation computation. This allows the user to simulate the effects of vehicles and other moving objects in the results. www.mwee.com/206903947 unique because it offers high frequency, broadband performance in a fully molded QFN package. The device is also fully matched and requires only a single, positive bias supply, making it an ideal low-cost solution for a widerange of applications. www.mwee.com/207000280 Certified wireless USB development kit accelerates native device designs based on Ripcord1 Staccato Communications’ Ripcord1 Development Kit (DVK) is an integrated development environment that accelerates native Wireless USB device designs based on the Ripcord1 family of singlechip, all-CMOS Certified Wireless USB solutions. The Ripcord1 DVK is built around the Ripcord Control Library (RCL), a fully abstracted software library that provides services to simplify the interface to the Ripcord1 IC and enables easy integration on a wide variety of platforms. Software compatibility of the RCL with all of Staccato’s Ripcord ICs allows for the seamless migration of designs that will work with the nextgeneration of devices on the company’s product roadmap. The integration of the Ripcord Control Library in the development kit reduces overall design complexity in a variety of applications including mobile handsets, digital cameras, printers, portable GPS disciplined oscillator features ultra-low-power consumption Jackson Labs has recently unveiled its FireFly product, an extremely small OCXObased GPS disciplined oscillator (GPSDO) that meets Stratum-1 requirements with very low-power consumption. The OCXO-based Fireﬂy delivers long-term performance similar to Atomic Frequency Standards, and supports both mobile such as vehicle-mounted and airborne applications and stationary applications. The FireFly GPSDO, which measures 1.25 cubic inches (or 20.48 cubic centimeters), provides Stratum-1 longterm performance of better than 10 parts per trillion (1E-011) averaged over 24 hours when locked to GPS at less than half the size of the smallest competitive products, said Jackson Labs. The GPS disciplined oscillator generates both an OCXOdriven 1 PPS output that is phase-synchronized to better than 100 ns rms to UTC, and a synchronized low-noise +12 dBm 10-MHz sine-wave output. The FireFly is easy to integrate in any application that requires a stable and accurate reference clock, and it can be monitored and controlled by an RS-232 port via industry-standard SCPI Commands. The FireFly is said to provide excellent phase noise and spurious suppression, and very low jitter at a power consumption of only 1.4-W typical. Custom frequencies and other nonstandard requirements can also be accommodated. www.mwee.com/207000304 media players, mass storage, and wireless audio/video. The RCL also allows designers to take advantage of the inherent benefits afforded by the Ripcord1 chip, which include low power, small form factor, and reduced system cost. Ripcord1 is listed on the USB-IF Integrators List for Certified Wireless USB Peripheral Silicon signifying that it has passed all of the compliance and interoperability tests required for Wireless USB certification. Ripcord1 has also previously passed WiMedia PHY and MAC certification, and US FCC and Japan TELEC regulatory certifications. www.mwee.com/207000307 Microwave Engineering Europe ● April 2008 ● www.mwee.com 036_MWEE.indd 36 28/03/08 15:15:46 http://www.mwee.com/207000280 http://www.mwee.com/206903947 http://www.mwee.com/207000304 http://www.mwee.com/207000307 http://www.mwee.com
