Inside Frequency Control

The Cassini Spacecraft, 20, of NASA died on Friday, September the 15th of 2017 while passing through Saturn's fierce atmosphere on the way to it's mysterious surface.

Here’s the scary thing…

Even if you sit for hours upon hours trying to set a precise initial frequency of an oscillator, it’s still going to drift and the oscillator will not be able maintain that frequency over the full course of its use. In this post, you’ll learn the MANY sources of frequency instability and why an Ultra-Stable OCXO may be the fix-all solution.

The #1 Most Critical Factor in High-End Radar & Communication Systems: Low Phase Noise

Phase noise, phase noise, phase noise.

If you’re involved with the design and implementation of communication systems, you most likely hear the term “phase noise” all the time (maybe more times than you’d like). 

There’s a good reason for all this phase noise chat. It’s one of the key factors that determines the overall success or failure of your radar or communications application. It’s even more important in intense environments where strong vibration or g-force is a concern.

Why is maintaining low phase noise such a concern in these applications and environments? And how can you solve the problems associated with the effects of phase noise? By the end of this article, you'll know why and how you should decrease phase noise in your applications.

If you’ve been following our blog, we recently announced the exciting hiring of both Atul Dhuria and Darshan Shah. Both have already been putting their noses to the grindstone and bringing new and innovative ideas to the company. More specifically, ideas around the future development of Satellite Communication and Commercial Space within Bliley and our products.

Spacecrafts must be designed to have very precise functionality when it comes to making the long journey to earth’s orbit and even beyond. Even simple vibrations can interfere with the spacecraft’s functionality during pre-launch transportation and powered flight.  In both cases, the spacecraft itself isn’t even being powered.
