Stop Spinning Your Wheels When Selecting Rotary Joints

May 16, 2014

Rotary joints based on rigid waveguide can provide high-performance, dependable connections in many commercial and military RF/microwave systems. But matching the right waveguide rotary joint to a particular application can call for a bit of “rotary joint know-how” beyond simply selecting proper waveguide sizes. These are precision components that can help keep high-frequency signals connected under a variety of conditions, and are available in different waveguide sizes as well as compact, coaxial versions as needed.

The Wonders of Waveguide

May 9, 2014

Waveguide is a technology uniquely synonymous with high-frequency RF/microwave electronics. Described simply, it is a form of hollow conductive metal tube that carries energy from one point to another. For RF/microwave use, it handles electromagnetic (EM) energy; forms of waveguide have also been used to carry acoustical and optical energy. Waveguide can be used to fashion a wide range of RF/microwave and even millimeter-wave components, including transmission lines, couplers, power dividers, and filters.

Wall St Drives Down RF Avenue

June 16, 2014

 In the first half of the year, MACOM has acquired Nitronex, Avago has acquired LSI, RFMD and TriQuint are merging, Cobham is acquiring Aeroflex, and most recently announced, Analog Devices is acquiring Hittite. My head is spinning with all of this consolidation, not to mention several other smaller acquisitions that happened during this period.  What is going on in the RF industry?  An industry that has been mostly made up of smaller to medium sized companies seems to be going large with all of these organizations turning into multi-billion dollar companies.

Making Microstrip Coupled Features Work

July 21, 2014

 The printed-circuit-board (PCB) material plays a major role in how microstrip transmission lines perform their duties in RF and microwave circuits, and it can be helpful to understand how certain PCB material characteristics contribute to the ways that microstrip transmission lines and their coupled features perform in these different high-frequency components.

Taming Discontinuities in Microwave Circuits

July 7, 2014

 Designing high-frequency microwave circuits and, with increasing frequency, millimeter-wave frequencies require for the most part laying out carefully conceived transmission lines to carry those high-frequency signals across a printed-circuit board (PCB). Of course, if the task of fabricating the PCB was simply a matter of adding circuit elements, such as resistors, capacitors, and inductors, to create the necessary frequency-domain/time-domain response for the PCB, it might go somewhat easier. But every PCB with high-frequency transmission lines must also manage any number of circuit discontinuities and junctions. Since these and similar discontinuities can be found on all but the simplest of RF/microwave circuits, the question is “How can the effects of these discontinuities be minimized through the thoughtful choice of PCB material?”

The Impact of CMOS Power Amplifiers on the Handset

July 8, 2013
Qualcomm recently made a big splash, announcing their RF360 product to accompany its transceiver and baseband chipsets for mobile handsets. To old radio guys like me, this brought back memories of the first integrated CMOS transceivers for mobile handsets. Back in the early 1980s, with AMPS cellular systems, the handset used discrete components in the transceiver. By the 1990s, when 2G systems were starting to ramp up, Qualcomm and other baseband modem suppliers suggested a migration to CMOS transceivers.

The Diagnostic Powers of Test

September 22, 2012

HendrenBrian Hendren, Senior RF and Microwave Applications Engineer, Tektronix Component Solutions takes over the Tek Talk blog and discusses prototyping for success:

In this day and age manufacturers are trying to drive costs out of every aspect of the production flow, and RF and microwave is no exception.  That means that every process step gets closely scrutinized. Specifically,“test” is one of the operations constantly under evaluation to understand the bare minimum needed to verify performance.  That approach is understandable because test is likely one of the most time consuming steps in the production flow, particularly when you include system set up time.

Microwave & RF Engineers…Communication is Key!

May 1, 2013

I recently agreed to co-chair the IEEE MTT-S Women in Engineering (WIE) / Women in Microwaves (WIM) organization. I have long been an advocate for advancing the cause of women in the world of RF and microwave engineering, actually back to my college days at Carnegie Mellon University (CMU) when I was one of only eight women in my EE graduating class of 110. Things have not improved much since then with women representing only 10 percent of the engineers in the U.S. today. Asia and Europe fair far better with approximately 40 percent and 20 percent respectively.
