RF & Wireless Components

RF & Wireless Components Components Tiny Bluetooth Low Energy SoC N o r d i c S e m i c o n d u c t o r announced the availability of a Wafer Level Chip Scale Package (WL-CSP) variant of its nRF52832 Bluetooth low energy (formerly known as Bluetooth Smart) System-on-Chip (SoC) that occupies a quarter of the footprint area of the standardpackaged Nordic nRF52832 and targets next-generation, high-performance wearables and space-constrained IoT applications. The nRF52832 WL-CSP has a super-compact 3.0 by 3.2 mm footprint compared to the standard 6.0 by 6.0 mm footprint of its larger but conventionallypackaged nRF52832 QFN48 cousin, yet offers the same full single-chip feature set and bestin-class, ultra-low-power application operation. This includes a powerful on-board 64 MHz ARM Cortex-M4F processor that enables protocol and application task processing to be completed in unprecedentedly short time-frames, thus allowing power-saving sleep modes to be entered much quickly compared to competing devices. Like the nRF52832, the nRF52832 WL-CSP features: 512 kB Flash and 64 kB RAM; on-chip NFC tag for consumerfriendly Touch-to-Pair; best-inclass ultra-high performance, ultra-low-power multi-protocol Bluetooth low energy, ANT, and proprietary 2.4 GHz radio; 5.5 mA peak RX/TX currents; an on-chip RF Balun; plus a unique fully-automatic power management system that makes achieving optimal power consumption easy for designers. The nRF52832 WL-CSP is compatible with Nordic’s Bluetooth 4.2 stacks and supporting SDKs including the latest S132 multi-role concurrent software stack, nRF5 SDK, nRF5 SDK for HomeKit, and nRF5 SDK for AirFuel (resonant wireless charging). ■ Nordic Semiconductor ASA www.nordicsemi.com News CST Announces Acquisition of IdemWorks Computer Simulation Technology AG (CST) announced the acquisition of Idem- Works s.r.l. (IdemWorks), an industry leading provider of modeling tools and services. Engineers working in a wide range of applications, including Signal/ Power Integrity and EMC verification in Digital, RF and Mixed/Signal design can look forward to enjoying greater synergies between IdEM and CST Studio Suite. IdEM is a user friendly tool for the generation of SPICE-ready macromodels of electrical interconnect structures such as packages, connectors, via fields, discontinuities up to backplane links and complete power delivery networks. Starting from their input-output port responses, derived from measurement or simulation, IdEM provides accurate, proven, passive and causal broadband computational models that can be used in any circuit simulation environment for reliable transient and AC analyses. “The IdemWorks and CST teams will work closely to develop a roadmap of efficient enhancements and integrations that will leverage the best capabilities of the combined IdemWorks and CST products,” stated Michelangelo Bandinu, CEO of IdemWorks. “We are very excited about the creative possibilities that this acquisition brings and are confident that this will provide significant benefits to our customers.” The IdemWorks team has a strong application-oriented scientific background which is key to solving challenging modeling problems and bringing innovation to the market. Customers benefit from the speed, accuracy and stability of models generated by IdEM and the experience that has been gathered through many years of developing software tools and consultancy. Prof. Stefano Grivet-Talocia, Founder of IdemWorks, says: “This acquisition is the natural evolution of IdemWorks. Since its foundation in 2007 as an academic spinoff, IdemWorks has been continuously growing, both in market share and in reputation. The time has come to combine our advanced model extraction algorithms with top-class field solver engines, and the technology leading set of tools in CST Studio Suite is the optimal choice for us. The planned tight integration between the two platforms will lead to significant innovation in the near future, with major benefits for end users and customers.” Through this acquisition, CST will gain access to complementary, state of the art modeling technologies, based on best-inclass algorithms. IdemWorks will continue developing, supporting and selling their modelling tools, thus maintaining customer business continuity. “IdemWorks products are recognized worldwide as the best-in-class solution available on the market to solve challenging modeling problems. We feel that the technology is a very good extension of our simulation capabilities and look forward to working with the team,” commented Dr. Bernhard Wagner, Managing Director, CST. “We are also aware of the strong and trusting relationship between IdemWorks and their customers, and feel committed to continue these relationships as seamlessly as possible.” ■ CST info@cst.com www.cst.com 38 hf-praxis 9/2016

RF & Wireless Components High-Q MLCCs for high temperature and high frequency applications Knowles Capacitors brand, Syfer, has just released a new addition to its range of High- Q MLCCs. Designated as the H series they are manufactured from a very stable, X8G High Q ceramic dielectric to provide ultra-low ESR, with excellent low loss performance and low power consumption, in high environmental temperature and high frequency systems. They exhibit no ageing effects, with stability under voltage and very low drift. The electrode system is optimized for the lowest possible ESR and provides low metal losses that result in flatter performance curves and reduced losses at higher frequencies. An extended operating temperature range of -55 to +150 ºC accommodates modern high density microelectronics requirements where environmental temperature could be high. They will find application in DC blocking, Impedance Matching, Coupling and Decoupling functions of PA module, LNA module and Antenna system of small cell or 5G networks – where environmental temperature is high as a result of high power generated in relatively small chambers. Automotive applications are also another area for potential use. With the excellent ESR performance and extended temperature range, Syfer’s H series High-Q MLCCs can contribute to improving power amplifier efficiency and long term reliability of systems – greatly reducing power loss, heat dissipation and decreased battery drain. 0603 and 0805 case sizes are released with immediate effect with 0402 size following shortly. ■ Knowles Capacitors www.knowlescapacitors.com News MBT appoints Link Microtek as UK Representative Massachusetts Bay Technologies, the US manufacturer of discrete semiconductor devices, has appointed RF and microwave component specialist Link Microtek as its exclusive representative in the UK and Ireland. Founded in 1999, MBT designs and manufactures a comprehensive range of silicon RF/microwave semiconductor devices at its facility in Stoughton, Massachusetts. Standard products include tuning varactors, PIN diodes, Schottky diodes, limiter diodes, step recovery diodes and various passive components. Commenting on the tie-up between the two companies, Stuart Hendry, Link Microtek’s sales director, said: “We are extremely pleased to be working in partnership with MBT. Their From left: Brian Fallon, MBT’s president; Stuart Hendry, Link Microtek’s sales director; and Charles Fallon, MBT’s vice president discrete semiconductor devices are a perfect complement to our product portfolio, and we are certain that a number of our existing customers will be very interested in what they have to offer. “One of their particular strengths is supplying components as replacements for other manufacturers’ obsolete parts, and the fact that they have their own wafer fab gives them total control over product quality and availability.” With operating frequencies ranging from 100 Hz to over 100 GHz, MBT’s products are suitable for use in a variety of commercial and military applications. Available package styles include ceramic and plastic surface mount, ceramic pill, glass axial leaded, beam lead and chip. Brian Fallon, president of MBT, was also enthusiastic about the new agreement: “As a well established supplier of RF and microwave components, Link Microtek has demonstrated not only first-class knowledge of the market but also real expertise in discrete semiconductor technology. We believe this will be a fruitful relationship and are excited about the opportunities that will open up for us in the UK and Ireland.” ■ Link Microtek Ltd. www.linkmicrotek.com Massachusetts Bay Technologies www.massbaytech.com hf-praxis 9/2016 39
