The Tesla Coil: A Basic RF Resonant Transformer

By |2020-05-20T14:36:45+00:00May 20th, 2020|Uncategorized|

The Tesla coil provides a high voltage demonstration of a resonant transformer. Although primarily used for entertainment purposes, with its long electrical arcs and noise, it also provides a path to understanding basic RF resonant circuits; just part of the many considerations involved when designing RF circuits. Overview of Design There are many paths one [...]

What was that? Ever go to a party and you’re one of the first to arrive?  You start a pleasant conversation and before you know it, as attenders start funneling in, find yourself yelling in the ear of the listener “what was that”?  The same thing happens      Figure 1 Electromagnetic participant examples [...]

More Power! Can you imagine life without your smartphone?  How could we possibly function?  Our entire life is now centralized in a single mobile location.  In a split second we can update our activities to 100’s of people, trade stock, binge watch our favorite show, summon a ride, order a pizza, and the list goes [...]

Using Time to Save Time Tuning Filters

By |2020-03-25T13:31:28+00:00March 25th, 2020|Design Innovation, RF Design, RF Filters|

In the world of wireless communication, the airwaves are continually getting more and more crowded. The need for filtering signals has always existed. The need for more precise and tighter spec’d filters is increasing. More stringent demands often come with a higher price tag due to difficulties in producibility. Tighter specs mean tighter dimensional requirements, [...]

Internet From The Stars: 21st Century Space Race

By |2020-02-13T14:36:03+00:00February 17th, 2020|Design Innovation, Leadership Insight, Product Development|

Two weeks ago, SpaceX launched it’s third successful mission placing 60 more Starlink satellites into low earth orbit, bringing the total number of global internet powering satellites to 180. That is far from the planned system completion threshold of 12,000, but it does establish that SpaceX has the formula down and isn’t going to stop [...]

Which Filter Response Type Is Best For My Application?

By |2020-02-05T16:04:22+00:00January 31st, 2020|RF Amplifier, RF Design, RF Filters|

Why is RF filtering so important? Simply put, filters reduce the interference in the environment that affects the performance of the communication system and reduce the interference caused by the communication system. Once you have identified the system level need for a filter, it’s now time to determine which filter response type will accommodate your [...]

The Benefits of a Tunable RF Filter

By |2020-02-18T18:37:54+00:00January 3rd, 2020|Product Development, RF Filters|

Filters are a staple of RF designers everywhere, and especially in applications where the integrity of the signal cannot be compromised. When you’re only concerned about a single frequency, it’s relatively easy to add in a fixed-tuned filter.  However, it becomes slightly more difficult when you need to cover multiple frequencies and can’t just utilize [...]

Spectral Regrowth: Stay in Your Lane

By |2020-01-22T13:53:01+00:00November 27th, 2019|RF Amplifier, RF Design, Testing, Uncategorized|

Modern communication systems are typically based on a framework of channels, where the frequency spectrum is divided into channels of a defined bandwidth and each signal is assigned to a particular channel.  This is analogous to a highway system being divided into lanes.  On a highway, it is undesirable for a car to cross into [...]
