RF & Wireless Wireless

RF & Wireless Wireless Brand New Coaxial GaAs MIC-based High Power Amplifiers Pasternack Enterprises, Inc. announced the release of eight new high power linear amplifiers that provide accurate signal amplification across a multitude of commercial and defense applications such as communications, radar and sensors, test instrumentation, telecom infrastructure, fixed microwave backhaul, commercial two-way radio, and many others. These GaAs PHEMT MMIC-based amplifiers operate from 0.8 GHz to 9.5 GHz and can be used as high power output amplifiers or driver amplifiers depending upon the system architecture. Pasternack’s new high power RF amplifiers provide a choice of gain levels, frequency ranges, power outputs, and exhibit gain performance ranging from 19 dB to 32.5 dB. These amps also offer competitive gain flatness from ±0.5 dB to ±2 dB and excellent third order intercept levels (IP3) from 38.5 dBm to 47 dBm. The company’s linear RF amplifiers are offered in various frequency ranges with optimized performance over the pertinent range and are specially designed to ensure the robustness of the modules and ease of use through features such as mounting holes in the body of the aluminum enclosure which assures a more effective heat dissipation path. The superior performance of Pasternack’s high power amplifiers is achieved through using GaAs PHEMP MMIC circuitry along with advanced hybrid integration techniques. The amplifiers are fully matched internally for input and output at 50 ohms which eliminates the customers’ need for any sensitive external RF tuning components. All of the new amplifiers are rated for operation over a -55 °C to +85 °C temperature range. ■ Pasternack Enterprises, Inc. www.pasternack.com Pasternack RF Amplifier Part Parameter (Typical) Units PE15A5004 PE15A5005 PE15A4011 PE15A5006 PE15A5007 PE15A4012 PE15A5008 PE15A5009 Frequency Range GHz 0.8 - 2.2 1.5 - 3.5 2.4 – 4.0 2.5 - 4.0 2.6 - 4.2 3.5 - 7.0 4.0 - 6.5 5.5 - 9.5 P1dB Output Power Min dBm 38 38.5 37 37.5 38 36.5 37.5 37.5 Small Signal Gain dB 30 19.5 32.5 19 19 26 19 23.5 Gain Flatness Max dB ±1.5 ±1.25 ±0.5 ±0.5 ±2.0 ±2.0 ±2.0 ±2.0 Output IP3 dBm 38.5 45 45 45 47 45 47 47 Noise Figure dB 10 10 5.5 8 9 11 12 8.5 Input Return Loss dB 19 15 11 10 19 13 15 13 Operating Temp.

With up to 75 dB shielding, these shielding enclosures protect effectively in noisy environments against RF interferences. RF shield enclosures are required for R&D, service and for high volume production. Easy one-hand-lift operation and balanced lid mechanism allow for tireless operation. “Our new ASB Series RF Shield enclosures are available in a great variety of sizes and can be equipped with ports and interfaces depending on customer’s needs,” said Wolfgang Damm, President of AWT Global and he continues, “high product quality guarantees ASB shielding boxes to maintain their shielding characteristics even after tens of thousands of test cycles.” ASB RF shield enclosures are available for frequencies from 400 to 6000 MHz and offer a shielding performance of up to 75 dB. They are offered in a variety of sizes ranging from 250 x 180 x 146 mm (9.8” x 7.0” x 5.7”) to 600 x 600 x 600 mm (23.6” x 23.6” x 23.6”) inner dimensions. ■ AWT Global, www.awt-global.com 50 hf-praxis 12/2014

RF & Wireless Software Industry’s First 5G Exploration Library from Keysight Keysight Technologies, Inc. introduced the Keysight EEsof EDA 5G Baseband Exploration Library. Providing ready-to-use reference signal processing intellectual property (IP) for 5G technology research, this industryfirst library dramatically increases the productivity for system architects and baseband physical layer (PHY) designers. Keysight’s 5G Baseband Exploration Library supports various 5G candidate waveforms for orthogonal and non-orthogonal multi-carrier communication systems, including advanced MIMO and beamforming signal processing. The library also provides transmitter and reference receiver modeling examples that can be easily re-designed to achieve optimal performance for comparison of each of the candidate standards proposals. The new library consists of source code, models, subsystems, simulation examples, and infrastructure components for the high quality, rapid development and verification of advanced digital modems using Keysight’s SystemVue electronic system level simulation platform. The source code instills algorithmic confidence and provides an independent self-documenting reference library that allows system architects, algorithm developers and baseband hardware designers to quickly replace and modify blocks and subsystems to meet the needs of their specific end product. SystemVue’s integrated simulation environment allows users to investigate, implement and verify their communications PHY signal processing designs with dynamic linklevel scenarios. The W1465 SystemVue System Architect simulation environment is used to develop innovative designs for R&D. Adding the new 5G Baseband Exploration Library to the mix provides: • Advanced digital signal processing blocks for 5G candidate waveform technologies. • End-to-end physical layer transmit and receive simulation models. • Signaling schemes for MIMO channels including spatial multiplexing, space-time coding and multiple detection methods. • Reference waveform generation to verify RF circuit designs. “Keysight provides the largest array of design and measurement solutions being applied to wireless research,” said Roger Nichols, Keysight’s 5G program manager. “We are excited to introduce this first of many 5G-focused solutions that accelerate deployment of the fifth generation of mobile wireless.” Keysight’s W1906BEL 5G Baseband Exploration Library will be available in late November as part of the new SystemVue 2014 release. Interested parties may request early access through enrollment in the SystemVue Early Access Program at www. keysight.com/find/eesof-systemvue-earlyaccess. Information about Keysight‘s 5G test and measurement solutions is available at www.keysight. com/find/5G. ■ Keysight Technologies, Inc. www.keysight.com Mouser Speeds Design with Launch of MultiSIM BLUE, Powered by NI Mouser Electronics announced the global release of MultiSIM BLUE, the NI Multisim Component Evaluator Mouser Edition. The global distributor of electronic components is introducing the new, all-inone circuit simulation tool, complete with integrated PCB layout and Bill of Materials (BOM). It allows you to scheme, simulate, PCB design, BOM export and purchase with one powerful integrated tool. Available via free download on Mouser.com, MultiSIM BLUE enables engineers to design and simulate circuits before laying them out in physical prototypes. MultiSIM BLUE adds features and functionality to provide engineers with an industry-standard SPICE simulation environment of electronic circuits using Mouser’s distributed components, including the newest in analog and mixed signal ICs, passive components, discrete semiconductors, power management ICs, connectors, and electromechanical components. Engineers can now visualize and evaluate linear performance, making this critical step of circuit design easier, faster and far more productive. Simulation is driven by the same advanced parser technology as NI Multisim software with support from BSIM and other advanced parameters. With MultiSIM BLUE, engineers can easily create schematics, simulate circuits and build printed circuit board layouts, thanks to a fully integrated tool chain. Part selection is made easy with BOM export to cart purchase capabilities.
