What Will the RF Industry Look Like in 10 Years? (New RF Technologies)

Posted by Bliley Technologies on Aug 30, 2021 6:30:00 AM

From smartphones to satellite service, GPS and more, RF technology is a feature of modern life that is so ubiquitous that many of us simply take it for granted.

Radio frequency engineering continues to help drive the world across many applications in both the public and private sectors. But technology advances so fast, it’s sometimes hard to predict what the world will look like in just a few years. Back in 2000, how many people outside the industry would have guessed that within 10 years, they’d be watching streaming videos on their phone?

The Secret to Low Phase Noise in Crystal Oscillator Circuits

Posted by Rob Rutkowski on Aug 26, 2021 9:06:00 AM

Quartz crystal oscillators are the high and mighty option for low phase noise and added frequency stability in circuit design. Yes, simple oscillators like those made with resistor-capacitor (RC) or inductor-capacitor (IC) resonators are fine for some circuits. But if you're dealing with higher performance applications in aerospace, military, and space industries... you're going to want a higher performance crystal oscillator that can maintain low phase noise & strong stability. Otherwise, you'll risk deviating from the very specific (and many times critical) center frequency selected for your design.

Common Misconceptions About Crystal Oscillator Stability

Posted by Bliley Technologies on Feb 2, 2020 10:14:00 AM

RF engineers would love to get their hands on ideal crystal oscillator circuits. That is, a quartz crystal oscillator that transmits at the designated frequency for the entire life of the device without any frequency deviation. Unfortunately, that ideal circuit world is a mathematical fantasy.

There are many factors that contribute to quartz oscillator stability and frequency drift issues. To prevent these problems as much as possible, having a firm understanding of precise frequency stability will help give you the tools to keep your applications performing optimally. But there's another problem...

Is a Swept Quartz Crystal Necessary in your Timing Application?

Posted by Rob Rutkowski on Dec 11, 2019 8:45:00 AM

What is a Swept Quartz Crystal?

Like many other things, radiation can impact a crystal oscillator's frequency. This is because radiation physically alters the quartz crystal inside the oscillator (changes position of weakly bound compensators that change the elastic constants of quartz). In some cases, radiation can even impact the crystal series resonance. The increase of resonance can be serious enough to cause the oscillator to stop oscillating if the crystal isn't radiation resistant. When a quartz crystal is manufactured to be radiation resistant, the crystal is referred to as a swept quartz crystal.
