For the reason that Fifties, the Worldwide Microwave Symposium (IMS) has been one of many preeminent occasions for RF and microwave engineers to assemble, current, trade concepts, and do enterprise. Although Covid restrictions and considerations have hampered the IMS occasions for the previous two years, this 12 months seems to have come again at almost full swing.
By opening day, there have been over 6,000 registrations, with extra to return. Over 400 exhibitors had cubicles at this occasion, and it felt simply as vibrant as IMS occasions of the previous. This text covers highlights of the exhibition and a number of the phrases on the road.
Exhibition highlights
Although IMS is a expertise convention, it doesn’t include the fanfare of many different excessive–expertise conferences. It’s far more of a B2B and engineer–to–engineer occasion, with a excessive degree of technical discourse. The crowds at IMS come to the exhibit to not see flashy shows however to have detailed technical discussions with colleagues, buddies, previous clients, and potential clients, in addition to to even listen in on opponents.
The RF/microwave business is comparatively small, and lots of people have already got contacts with most of the corporations/organizations they might do enterprise with. In lots of instances, IMS is an opportunity for an in depth, in–particular person dialogue. For a lot of, although, they’re locked in an engineering closet and are available simply to see what’s new and probably discover an thrilling new resolution to an previous drawback.
Within the spirit of that final thought, the next are a number of highlights of expertise options mentioned by a number of corporations at their cubicles.
Compass Applied sciences/Copper Mountain Applied sciences: Radome scanning system
Compass Applied sciences Group LLC, in collaboration with Copper Mountain Applied sciences, made a radome scanning system that may be repositioned alongside the curve of a radome floor whereas minimizing the affect on the VNA measurements. The radome scanning system consists of a two–port Copper Mountain VNA with out the everyday exterior packaging. The VNA is mounted in a customized 3D–printed housing, with the take a look at results in the two–GHz to 18–GHz probes immediately soldered to the VNA board.
The mounting system, which within the demo is hand–operated however may very well be mounted on a robot for a totally autonomous radome scanning system, is both 3D–printed or in any other case customized–fabricated, which makes this a cool demonstration of what some ingenuity and a compact VNA can obtain.
Fortify & Rogers Company: 3D–printed dielectrics with metallization
Fortify is a producer of 3D printers and an innovator of 3D–printing expertise. At IMS, the corporate demoed some attention-grabbing new capabilities with Rogers’s Radix 3D–printable low–loss polymer.
Apart from a number of 3D–printed luneburg–fashion lenses and radomes, Fortify demoed metallized 3D buildings, similar to planar transmission traces and antenna arrays with feed buildings and radiators. The cool side of that is that direct metallization of 3D–printable elements implies that a single course of can be utilized to manufacture complicated RF/microwave/millimeter–wave (mmWave) elements with extremely low lead occasions.
Vaunix: Compact daisy–chainable programmable attenuators and 40–GHz sign generator
Although Vaunix has been promoting compact programmable attenuator modules for a while, at IMS 2022, the corporate had one thing new to indicate. Apart from a brand new 40–GHz sign generator, Vaunix introduced a brand new programmable attenuator product that features a daisy–chaining function.
With this new function, a PC with a single USB connection can management and energy a collection of programmable attenuators which can be interconnected with their jumpers. Earlier fashions required every programmable attenuator to be linked through USB to the PC, which frequently necessitates a USB hub.
Sign Hound: Compact PC–managed sign generator to 43.5 GHz
Sign Hound is thought for making very reasonably priced however high quality PC–pushed sign analyzers and different PC–pushed take a look at devices. This 12 months, the corporate demoed a 43.5–GHz spectrum analyzer with 160 MHz of instantaneous bandwidth with calibrated I/Q seize. The I/Q seize is accessible via a block switch of a two–second I/Q buffer through USB 3.0. For simply over $20k, this analyzer is an unbelievable deal for a really in–demand frequency vary that may attain the brand new mmWave 5G (excessive–band 5G) frequencies.
Dongwoo High quality–Chem Co.: Clear, on–show mmWave antenna
An attention-grabbing new exhibitor at IMS, Dongwoo demoed quite a lot of clear antennas, together with an on–show mmWave antenna that may accommodate the brand new 5G frequency bands. One other was a clear antenna that covers the sub–6–GHz Wi–Fi bands. An instance utility of such an antenna is mounting the mobile antenna on clear movies to the glass of the entrance of a bus, which supposedly dramatically improves the reception of the mobile modem that gives Wi–Fi for the bus methods.
Phrase on the road
The phrase on the road is way the identical because it has been in years previous. There’s a basic scarcity of RF engineers, with a considerable age hole between RF engineers nearing retirement and new engineers popping out of college. Which means that gross sales representatives used to working with engineers and acquisition of us from their identical technology need to adapt their methods and communication to engineers and business professionals that may very well be their kids, or virtually grandchildren in some instances.
The brand new regular that began throughout Covid has additionally modified the dynamic for gross sales and advertising efforts. Fewer engineers and RF professionals are within the workplace besides once they need to be. This makes visiting an organization and talking to engineers and RF professionals considerably difficult, as these people usually come into the workplace for a number of particular duties and e-book their days with inner conferences and demanding conferences, with little room for networking or assembly a gross sales rep.
There have been over 60 new exhibitors at IMS 2022, which is sort of the quantity. Some have been corporations from abroad, others have been new RF corporations, and there have been even some corporations probably simply at IMS to recruit (I’m speaking about you, Apple). Apart from that, it was enterprise as typical.
Conclusion
Although economies undergo around the globe and provide chain points plague many industries, the RF/microwave business is trucking together with continued innovation and developments.
A lot of the push for enhanced wi-fi communications, together with satellite tv for pc, immediately impacts the RF business, in addition to international conflicts resulting in elevated buying of important RF electronics and methods.
