How Does Satellite Communication Work From Space?

Posted by Rob Rutkowski on Sep 28, 2017 7:48:00 AM

The international space station (ISS) is traveling in orbit around our earth at about 217 Miles (350 km) above earth’s surface. That’s equal to about 1,148,294 feet (yes, over 1 MILLION feet) or 350,000 meters above you. Those are some crazy heights! The ISS and other satellite communication devices must be able to cover a ton of earth’s surface from there, right?

Maybe. Maybe not. Let’s explore...

5 Reasons Why Choosing an Ultra-Stable OCXO Might be Smart

Posted by Rob Rutkowski on Aug 9, 2017 7:32:00 AM

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.

RADAR 101

Posted by Bliley Technologies on Jul 25, 2017 6:30:00 AM

Radar technology has become extremely important in today's world.

They help guide the freighters which ship the electronics, clothing, and countless other products we use every day to our shores.

They help meteorologists detect advanced weather patterns to produce the weather forecasts we see every morning on the news.

Further, radar is used for:

  • Air traffic control and navigation
  • Military applications
  • Astronomical and meteorological study
  • Law enforcement purposes. (You can thank the radars in police radar guns for that speeding ticket you may have gotten.) 
  • Continually growing amounts of uses
Clearly radar is important for many reasons. Here's a deeper look into what exactly radar technology is and what makes it so effective for many applications.

Breaking Down the RF Spectrum – Which Bandwidth is Best for Your Application?

Posted by Bliley Technologies on Jul 5, 2017 6:30:00 AM

The harnessing of the electromagnetic spectrum represents one of the greatest technological leaps in human history. So many luxuries and necessities, products, services, and systems we take for granted are all, in some way, linked to electromagnetic technologies. More specifically, to those which make use of the RF spectrum. But as anyone who works in the industry knows, the first order of business when designing a new product or system is to determine what part of RF spectrum will be the best fit for the application.

Low Phase Noise Solutions for Radar & Communication Systems

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

Phase noise…phase noise…phase noise!

If you’re anyone involved with the design and implementation of communication systems, you most likely hear that word “phase noise” all the time. Maybe even more times than you’d like.  Get used to it for now, it will be used a lot in this post.

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 of an importance in intense environments where strong vibration or g-force is a concern.

So the question is, why is maintaining low phase noise such a concern in these applications and environments? And of course, that question wouldn’t be worth asking unless we also answered how to solve any problems associated with the effects of phase noise. You will know how and why you should decrease phase noise in applications by the end of this article.

A Beginner’s Guide to Understanding CMOS Clocks

Posted by Bliley Technologies on Jun 13, 2017 6:30:00 AM

There are so many different devices and products for frequency generation and timing, but between all the acronyms and complex terminology of the RF industry, it can be confusing trying to understand what each type of clock or oscillator does, and what the best applications for each of them are. In this article, we’re going to help clear up some of the confusion, with a specific emphasis on CMOS clocks. We’ll cover what these devices are, why they are important, and how to know if one of these clocks is the best fit for your application.
