NanoSemi was among the newer companies creating a stir at IMS 2017. Many firms are gaining significant performance improvements using its linearization approach. The team originally came out of MIT.
Analog Devices was eager to demonstrate the new AD9375 integrated wideband RF transceiver. The AD9375 offers the benefit of integrated digital pre-distortion (DPD).
A demo at Mitsubishi Electric spotlights a GaN Doherty amplifier with a wide-bandwidth, 600-MHz design. It enables the handling of up to 10 LTE carriers while boasting instantaneous bandwidth of 200 MHz. Thanks to a DPD algorithm, it also can be linearized to meet the needs of multiple carriers.
NXP's Gavin Smith explains how the company is using its new 65-v LDMOS solutions to satisfy industrial heating applications like welding and drying. The MRFX1K80H provides 1800 W CW from 1.8 to 470 MHz.
70 GHz GORE® VNA Microwave/RF Test Assemblies
Keysight Technologies showcased its new modular signal generator. With an eye on 5G design verification, complex waveforms can be generated at frequencies as high as 44 GHz.
Signal Hound displayed a prototype of its new SM200A spectrum analyzer. “We’ve now got ourselves a high-performance 20-GHz spectrum analyzer with USB-processing,” said Bruce Devine, Signal Hound’s CEO.
Anritsu demonstrated that it can simultaneously deliver vector network analysis (VNA) and spectrum analysis on-wafer probing solutions to 110 GHz. The company’s nonlinear-transmission-line (NLTL) millimeter-wave modules make this testing possible.
Here, Michel Durr and Stephane Bailly explain the unique research capabilities of CEA Leti.
A fun find and topic at the Infineon booth was the potential for radar applications in the home and beyond. Radar is much smarter than infrared and could slowly turn on a street light as a person approaches and then slowly dim while knowing not to do that for a rodent, for example. Infineon's Alzon Canilao controls volume, a playlist, and more via gesture recognition to demo the company's 60-GHz radar with antenna in package.
GORE® PHASEFLEX® Microwave/RF Test Assemblies, Type 0N for High Density Test/Interconnection
The Leti booth highlights an ultra-narrowband transceiver called the Foxy chip because it is compatible with the Sigfox protocol. It is low cost, low power, and bidirectional, beating Sigfox's request to support 100 bits/s both ways. It doesn't require an MCU and includes integrated nonvolatile memory that is programmed for applications like IoT.
Boonton Electronics demonstrated its RTP5006 real-time peak power sensor. In this demo, the power sensor is being used for Wi-Fi testing to show its real-time power measurement capability.
While 5G and military were the focus of many products and demos at this year's show, the Internet of Things and sensing also were popular technology drivers. Here, Art Aguayo from Rogers talks to Microwaves & RF's Nancy Friedrich about the Kappa 438 laminates and how they satisfy applications that need higher specifications but not full RF capabilities. Carrier-grade WiFi and IoT both benefit from the resulting gain increase in the antenna circuitry.
Alexander Chenakin proudly displays his first product announcement since joining Micro Lambda Wireless. Dubbed the Luxyn, the MLVS-0520 covers 50 MHz to 21 GHz. It provides 0.001-Hz frequency resolution and 50-(lower case Greek mu)s switching speed. At 100 kHz, for example, typical phase noise is -155 at 50 MHz and -125 at 10 GHz.
Here, Cyril Furio, head of sales and business development at Exxelia poses at the booth. Among the company’s products are high-Q capacitors in a range of standard sizes.
MACOM’s Industry-Leading GaN on Silicon High Power RF Products
Making inroads into the US microwave market is Morion Inc., an 80-year-old company based in St. Petersburg, Russia. The firm's quartz-oscillator families are designed with a focus on precision. They also promise stability, such as long-term frequency stability to +/-5*10-9 per year and +/-5*10-8 per 10 years. Pictured are James Meyers and Alina Tchenakina.
IMS 2017 kicked off with a performance by dancers, drummers, and other performers to showcase the native culture in the "gathering place," a spot to sit, chat, or work in the middle of this year's show floor.
In this MicroApps presentation, Paul Blount from Custom MMIC discussed the importance of managing phase noise. The company now offers a line of low-phase-noise amplifiers (LPNAs).
In addition to being a huge networking and deal-making event, IMS is a place where long-time friends come together. Here, Microwaves & RF's Nancy Friedrich gets an annual hello and some insight on gallium nitride from Toshi Nakamura from Toshiba America Electronic Components (TAEC).
Part of the fun of IMS is meeting students. Many of them come from different parts of the world. Shaunel Walker, pictured here, is studying at South Africa's University of Pretoria. He has successfully used microwave components to cut costs in radio-astronomy equipment, which led to him presenting to the Institute of Astronomy and attending IMS as a bonus. Hawaii is home to the famous Mauna Kea Observatories.
A talk on James Clerk Maxwell from Sonnet Software's Jim Rautio has become an annual IMS tradition. Even though Rautio has studied and worked in electromagnetics throughout his career, he notes that Maxwell's book is best approached just a page or two at a time.
It looks like Microwaves & RF's Nancy Friedrich is at IMS, but thanks to virtual reality--using the HTC Vive headset--she is stepping through the inside of a circuit. This capability is enabled by the Empire XPU software from IMST. The user can control which way he or she travels through complex 3D models including the inside of the design.
When IMS welcomes students from local schools, the industry gets an opportunity to share its knowledge and pique the interest of the next generation. Here, students enjoy hearing about Wolfspeed's new gallium-nitride (GaN) MMICs for S-band applications from Brad Millon.
Test and measurement companies provide a lot of eye candy at IMS as they trot out groundbreaking advances to enable the latest developments in communications and defense. Here, our own Chris DeMartino chats with Faride Akretch at the Rohde & Schwarz booth. The firm announced the FSWP phase noise and VCO tester, which offers a spectrum analyzer and phase-noise tester in one box. It boasts phase-noise sensitivity of -172 dBc (1 Hz) at a 1-GHz carrier with a 10-MHz offset.
This display highlights some of the capabilities of WIN Semiconductors. The firm put over $20 million into organic R&D last year. Due to the majority of its business being in the handset, the company is active in 5G. Russ Wagner notes that nothing is concrete yet as the industry weighs options ranging from GaN to millimeter wave.
According to NXP's Suhail Agwani, 5G is a game changer, not just the next evolution of mobile communications. 5G will provide new revenue streams of which the industry and carriers haven't yet envisioned. With gigabit speeds on phones, the telecom industry will be thinking beyond the handset and finding opportunities to extract more revenue from handset-based communications.
Here, Microwaves & RF's Chris DeMartino chats with Texas Instruments' Simon Damphousse about the company's phase-locked-loop/VCO combo.
Chloe Rolland proudly stands with the first NoiseXT design she has worked on, the PNG-A. Having joined the company only six months ago, Rolland is especially proud of the instrument's precisely defined phase noise. The phase-noise generator delivers a signal with mathematically computed phase noise in real time.
