miscelaneous Half-bridge evaluation board simplifies GaN transistor testing A manufacturer of gallium nitride power transistors, GaN Systems has launched a half-bridge evaluation board which demonstrates the performance of its GaN enhancement mode power semiconductors in real power circuits. The fully functional GS66508T-EVBHB Evaluation Board is easily configured into any half-bridge-based topology, including synchronous boost and buck conversion modes, as well as pulsed switching to evaluate transistor waveforms. Accompanied by a Quick Start Instruction Guide and YouTube video links, the Evaluation Board can be installed and used in minutes. Each development kit comes with full documentation, including Billof Materials component part numbers, PCB layout and thermal management, and a gate drive circuit reference design to help system engineers develop their products. Designed to provide electrical engineers with a complete working power stage, the evaluation board consists of two 650 V, 30 A GS66508T GaN FETs, half-bridge gate drivers, a gate drive power supply, and heatsink. The GS66508T high power transistors are based on GaN Systems’ proprietary Island Technology® and belong to its 650 V family of high density devices which achieve extremely efficient power conversion with fast switching speeds over 100 V/nS and ultra-low thermal losses. The 30 A / 50 mΩ GS66508T GaN power transistors are top-side cooled, and feature near chip-scale, thermally-efficient GaNPX packaging. At 1.5 kW, this device’s power conversion efficiency is rated at 98.7%, a value which can be reproduced in the owner’s lab. GaN Systems Inc. www.gansystems.com Startup offers all-in-one 2G/3G/4G front-end Morfis Semiconductor Inc. (Irvine, Calif.), a startup founded in 2013, has announced it has developed a single-die flip-chip RF front end to support all 2G/3G/4G LTE frequency bands. The chip does this without compromising efficiency and linearity the company claims in a press release. The company plans to exhibit at the Consumer Electronics Show to take place in Las Vegas in January and to show there a multi-mode, multiband power amplifier and its RF front-end. Morfis is sampling special customers and mass production is scheduled to start in 2Q16. The company staff has been drawn from other RF companies in the area according to LinkedIn filings. Charlie Chen is CTO and was previously engineering fellow and director of engineering at RF Axis Inc. (Irvine, Calif.). Yun Shi, who was previously with Qualcomm, is director of operations and Zhan Xu, previously with TriQuint Semiconductor, is an engineering fellow at Morfis. Morfis Semiconductor Inc. www.morfis.com Advanced Bluetooth Smart remote reference design Available now, the nRFready Smart Remote 3 is a complete state-of-the-art hardware and software Bluetooth Smart reference design featuring voice input control, 39 programmable buttons, 6-axis motion sensing, and multi-touch trackpad The reference design that is said to make the development of advanced Bluetooth® Smart remotes as easy as clicking on a list of check box options, and so minimizing time-to-market and unnecessary design risk. Targeting remote control OEMs/ODMs and smart TV, set-top box, and digital media device manufacturers, the nRFready Smart Remote 3 reference design is designed to deliver a rich, intuitive, and engaging end-user experience. It employs state-of-the-art voice input and speech recognition control, a 6-axis motion sensing ‘Air-mouse’, multi-touch trackpad technology, plus 39 developer-programmable buttons and legacy IR hardware support (to control IR-only products). In operation, the nRFready Smart Remote 3 reference design employs Nordic’s nRF51822 System-on-Chip (SoC) and so is designed to work as an add-on for Nordic’s existing nRF51 Development Kit (DK).
