RF & Wireless Products 20 GHz Distributed Amp Offers Positive Bias Custom MMIC is offering a new device from their growing MMIC library of standard products. The CMD173 is a wideband GaAs MMIC distributed amplifier die for applications from DC to 20 GHz. This device delivers greater than 15 dB of gain with a corresponding output 1 dB compression point of +18 dBm, and a noise figure of 1.5 dB at 8 GHz. The CMD173 is an all-positive bias design, thus eliminating complicated and costly sequencing circuits while also simplifying board layout. In addition, the use of on-chip tracking circuits delivers consistent performance over temperature and process variation. The CMD173 is a 50 Ohm matched design that offers full passivation for increased reliability and moisture protection. The device does require off-chip bias networks, which is typical of this amplifier topology. ■ CustomMMIC http://custommmic.com/Product- Library/Amplifiers/ RFMW Introduces Differential IF Attenuator from Skyworks Solutions RFMW Ltd. announces design and sales support for the SKY12408-321LF differential IF attenuator. This GaAs pHEMT, two-bit attenuator I/C offers two states, a through path insertion loss of 0.3 dB, or 6 dB of attenuation. In a differential system, the attenuator presents a 100 Ohms impedance, but can be used as two single-ended attenuators, each with a 50 Ohms impedance. The SKY12408-321LF operates from 50 MHz to 600 MHz and is provided in a 3x3 mm 12-pin QFN package particularly suited for 100 Ohms differential systems for which high attenuation accuracy, low insertion loss, and low intermodulation products are required. A 12 dB version of this attenuator is available as the SKY12407-321LF with a pin compatible footprint. ■ Skyworks Solutions Stocking Distributor, RFMW, Ltd. info@rfmw.com Wireless LFOC Optical Link Outdoor Cabinet for Satellite Ground Station Applications AR Receiver Systems has introduced a DSP-based emissions receiver that has the speed and accuracy to reduce test time from days to minutes.

RF & Wireless Software CST STUDIO SUITE 2013 The increasingly complex tasks design engineers face today require a large number of sometimes specialised features. Simulation software vendors such as CST have enhanced their tools to accommodate these requirements. The continuously extended feature set in CST STU- DIO SUITE® has resulted in an impressive number of settings and options for the engineer to choose from. CST STUDIO SUITE 2013 has undergone a major redesign in order to escort the engineer on his way through his simulation projects. This guidance starts directly after opening the software. A project wizard helps set-up the software to meet a particular application type’s requirements and provide the relevant results. This configuration can be modified by the user based on the experience gathered on-site to deal with the specific application characteristics. The modified configuration can be stored and reused easily. A very significant and obvious change in the user interface is the introduction of the Ribbon. The Ribbon, as implemented in CST STU- DIO SUITE, not only groups features and menus, it also guides the engineer through the simulation process, only showing the currently active or relevant options. The performance improvements in CST STU- DIO SUITE are manifold and stretch over the entire range of solvers. The CST MICROWAVE STUDIO® (CST MWS®) transient solver, for example, benefits from a quicker matrix set-up, the solver runs faster employing the latest Intel® technology, and is able to deal with larger problems. “With CSTSTUDIO SUITE 2013 we are responding to our customer wishesforan easier workflow without sacrjficing the functionality or versatility of our software,” said Dr. Martin Timm, Marketing Director, CST. “Besides this, we have kept ourfocus on performance improvement. To provide efficient and well integrated solutions is key to our company’s success.” ■ CST, www.cst.com Agilent Technologies Ships Newest EMPro Software Release for Analyzing 3-D Electromagnetic Effects Agilent Technologies Inc. announced shipment of EMPro 2012 , its 3-D electromagnetic simulation software. EMPro 2012 allows designers to more easily create 3-D models and analyze the electrical performance of packages, connectors, antennas, and other RF and high-speed components. It delivers a number of critical features for new and existing EMPro users, including an enhanced integration between EMPro and Advanced Design System, enabling users to save EMPro projects as ADS libraries; availability of 3-D models in ADS as schematic and layout views; and availability of parameters created in EMPro in ADS for EM sweep/optimization.Additionally, changes made in EMPro now dynamically update in ADS, also a low-frequency analysis algorithm that enables stable, accurate results down to very low frequencies (below100 MHz, including at DC). The Faster Finite Element Method (FEM) simulations (1.4X compared with EMPro 2011) stemming from technology advancements that increase the robustness and speed (two to three times faster) of the FEM mesher. Currently supported Agilent customers interested in the EMPro 2012 technologies, applications and capabilities should contact their local applications engineer or field sales person for more information. ■ Agilent Technologies www.agilent.com Products 35W GaN Transistor from TriQuint Semiconductor R F M W, L t d . announces design and sales support for TriQuint Semiconductor‘s T1G4003532-FL, DC - 3.5 GHz GaN transistor offering up to 37 W P3 dB.
