So much of what defines our modern lives is made possible through radio wave technology, which has changed the world in ways the first researchers could never have anticipated. But where did anyone get the idea that radio waves existed in the first place, and that they could be harnessed for wireless communication? It’s a fascinating story that continues to unfold to this day. Let’s go back to the beginning to understand how this technology has evolved.

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...

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.

Inside The VCXO: Performance and Applications

[fa icon="calendar'] Apr 6, 2017 6:42:00 AM / by Rob Rutkowski posted in crystals, RF

[fa icon="comment"] 0 Comments

Does your application require a super stable frequency source? How about the ability of the frequency source to be fine-tuned? Sounds like a Voltage Controlled Crystal Oscillators (VCXO) may be a great choice for your specific needs! By using a crystal oscillator as the basis of the circuit in a VCXO, high levels of frequency stability and low levels of phase noise can be maintained while still being able to control the frequency over a small range.
