RF & Wireless Software Antenna Magus Version 2017 Released Magus and CST – Computer Simulation Technology AG announced the release of Antenna Magus 2017, the latest version of the leading antenna design tool. The latest edition includes several new antennas and design updates. Antenna Magus includes over 300 antennas, and the Specification-based workflow introduced in 2016 allows users to find, design and export suitable antennas based on their requirements. The 2017 version introduces 13 new types. Four specialized horn antennas have been added – the smooth spline profiled pyramidal horn, the 4 waveguide-fed dual polarized pyramidal horn antenna, the waveguide-fed pyramidal array and the TEM horn with magnetic dipoles (or “Koshelev antenna”). There are also five antennas commonly used in RF application notes and reference designs. These are standard antennas such the PIFA and the meandering monopole, which are provided by RF component manufacturers for testing during product development. With Antenna Magus, these can now be customized for different frequencies or different substrates, and parametric models can be directly created for 3D simulation with CST Studio Suite. Finally, there are four other antennas for special applications: the square truncated capacitively-pin-fed circularly polarized patch, the self-phased backfire quadrifilar helix, the six mode loop antenna and the center-fed linear resonant waveguide slot array with longitudinal broad-wall slots. The 2017 version also sees improvements to the Specification and Array Design workflows to streamline the design process. In addition, Antenna Magus is now entirely 64-bit and various performance improvements have been made to individual features. Meanwhile, CST customers who have both CST Studio Suite and Antenna Magus can now manage both licenses within the same tool. ■ CST AG www.cst.com Magus (Pty) Ltd. www.antennamagus.com Products Skyworks Enables Sierra Wireless‘ HL Series for IoT Applications Skyworks Solutions, Inc. announced that Sierra Wireless is leveraging a broad suite of Skyworks‘ 3G/4G connectivity solutions to power their AirPrime HL Series wireless modules targeting machine-to-machine (M2M) and device-to-cloud applications. In total, Sierra Wireless is utilizing 17 Skyworks devices spanning high performance multimode, multiband power amplifiers, transmit/receive front-end modules, RF switches and DC-DC converters. With the integration of Skyworks‘ devices, Sierra Wireless‘ modules uniquely combine voice and connectivity functionality that can be deployed in any region and on any wireless mobile network. According to a GSMA Intelligence report, at its current rate of trajectory, global cellular M2M connections are forecast to reach close to one billion by 2020, growing at a 25 percent per year compound annual growth rate from 2015 to 2020. ■ Skyworks, Inc. sales@skyworksinc.com www.skyworksinc.com New LNA Operates from 1559 to 1606 MHz Skyworks is pleased to introduce the SKY65623-682LF, a low noise amplifier (LNA) designed for applications such as wearables, asset trackers, navigation devices, action cameras and more. This discrete LNA is optimized to operate from 1559 to 1606 MHz, has a very low current (1 mA @ 1.8 V supply) and single power supply (1.5 to 3.6 V range) for design flexibility and simplicity. The device’s broad frequency range covers GPS L1, GLONASS, Galileo and Compass navigation systems and it minimizes external components thereby reducing the bill of materials for OEMs. The SKY65623-682LF comes in an extremely compact form factor (5L QFN 0.8 x 0.8 mm package), ideal for low-power Internet of Things (IoT) devices. ■ Skyworks, Inc. sales@skyworksinc.com www.skyworksinc.com Embedded Global 3G Cellular Module with Linux-based Application Processor Richardson RFPD, Inc. announced the availability and full design support capabilities for an embedded cellular module from Sierra Wireless. The WP8548 is part of Sierra Wireless’ AirPrime WP Series, which provides an integrated device-tocloud architecture enabling IoT developers to build a Linux-based product on a single module and seamlessly send valuable user and product data to the cloud. Offering an application processor running the open source Legato platform, GNSS receiver, and cellular modem with an ultra-low power domain, WP modules reduce system complexity and time-to-market. Key features of the WP8548 include: • Region: Global • 3G UMTS/HSPA frequency bands: B1, B2, B5, B6, B8, B19 • 2G EDGE/GSM/GPRS frequency bands: 850, 900, 1800, 1900 MHz • Regulatory approvals: CE, FCC, PTCRB, GCF, IC, JRF/JPA, NCC • Carrier approval: AT&T • Location services: GPS, GLONASS, Galileo ■ Richardson RFPD, Inc. www.richardsonrfpd.com 76 hf-praxis 6/2017

RF & Wireless Products GaN Amplifier Provides High Power for Weather/Marine Radar Band 1 Uplink BAW Filter Offers Low Loss Antennas Tiny new horn antennas aid testing of 5G-mm-wave equipment RFMW, Ltd. announced design and sales support for a 9 to 10 GHz, 35 watt, GaN power amplifier targeted towards weather and marine radar applications. The Qorvo TGA2622-SM provides a saturated output power of 45.5 dBm with 18 dBm input. Power added efficiency is >42% and large signal gain is 27.5 dB. For non-saturated applications, small signal gain is >30 dB. The TGA2622-SM requires a 28 V bias capable of 290 mA and comes in a 7 x 7 mm air-cavity QFN package. ■ RFMW, Ltd. info@rfmw.com www.rfmw.com UltraCMOS Power Limiter Application Note RFMW, Ltd. announced availability of a new application note. Peregrine Semiconductor’s UltraCMOS power limiters provide a monolithic alternative to discrete, PIN-diode limiters. They reduce design complexity by offering a drop-in solution with no external bias components. The application note is titled UltraCMOS Power Limiter Modes and Applications and explains how Peregrine’s power limiters have two operating modes: power limiting and power reflecting.

RFMW, Ltd. info@rfmw.com www.rfmw.com Link Microtek, manufacturer of RF and microwave components and subsystems, has unveiled a new family of miniature horn antennas that are designed to be used for millimetre-wave testing in 5G developments and EMC compliance. Ideal for test houses or manufacturers of E-band radio communications equipment, the AMHA-V1 series of horns can be utilized as either transmitters or receivers for measurements of products’ electromagnetic susceptibility or emissions in accordance with international EMC standards laid down by organisations such as IEC, ISO and CISPR. The series consists of six models with operating frequency bands starting from 40 – 60 GHz and rising all the way up to 170 – 260 GHz to allow measurement of harmonics. The smallest unit, covering the highest frequency band, is only 16,6 mm in length, while its WR4 waveguide opening has inner dimensions of just 1,09 x 0,55 m. All six horns in the range deliver a typical gain of 20 – 23 dBi and feature a modified standard flange design to ensure correct mounting within the test rig. Designed and manufactured at Link Microtek’s facility in Basingstoke, UK, the AMHA-V1 millimetre-wave horns are accurately machined for optimum performance and can be fabricated from either brass or aluminium with a black satin paint finish. ■ Link Microtek www.linkmicrotek.com hf-praxis 6/2017 77
