The Secret to Maintaining Low Phase Noise in Oscillator Circuits

Posted by Rob Rutkowski on Feb 20, 2020 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.

19 Popular Cube Satellite Companies in Today's Market

Posted by Rob Rutkowski on Feb 4, 2020 7:28:00 AM

Welcome to the new world of CubeSat Manufacturers! These small satellites are becoming more and more popular in today’s new space industry. Their increasing popularity is mostly because of their small, lightweight, and inexpensive designs. The standard 1U Cube Satellite is 10cm x 10cm x 10cm in size. However, since their inception in 1999, new Cube Satellite companies have developed more variations in size to meet desired payload levels. A 1.5U, 2U, 3U, 6U, 8U, 12U etc. are now offered to meet customer's growing specifications.

6 Emerging PNT Technologies & Solutions of the Future

Posted by Rob Rutkowski on Jan 7, 2020 8:42:08 AM

The U.S Department of Homeland Security considers 13 of the nation’s 16 critical infrastructure sectors to be ‘critically dependent’ on PNT technology. Also, a loss of PNT would cost the U.S an estimated $10 BILLION a day. Not only do many everyday consumers use PNT & GPS on a daily basis, it's also crucial for military and intelligence operations. Other industries that strongly rely on GPS based PNT include

  • Radio communications
  • Network synchronization
  • Intelligence systems
  • Information gathering
  • Cruise missiles
  • Weapons systems
  • Electronic warfare
In this post we're going to cover some of the challenges facing PNT today as well as 6 emerging PNT technologies and solutions that will revolutionize the future.

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.
