Vodafone & Nokia Team Up for the Moon's First Mobile Phone Network

Posted by Bliley Technologies on May 8, 2018 8:06:00 AM

A Berlin-based team known as PTScientists (Part Time Scientists) will be celebrating the 50th anniversary of the Apollo 11 moon landing in high-style in 2019. The group was a participant in the private race to the moon, the Google Lunar X Prize, which will wrap up this year without a winner. Their mission for 2019? To bring a 4G wireless mobile network to the moon!

How OCXOs Establish Precise Frequency Control

Posted by Bliley Technologies on Apr 3, 2018 6:30:00 AM

RF engineers are aware that temperature variations are the most significant factor contributing to frequency drift in crystal oscillators. Other variables affecting frequency output, such as humidity and pressure, can be easily alleviated with a hermetically sealed packaging of the crystal in a vacuum, or in an inert gas such as nitrogen. Controlling temperature for precise frequency output in a crystal oscillator circuit, however, requires a higher level of electronic RF design ingenuity. Enter... The Oven Controlled Crystal Oscillator (OCXO).

Common Misconceptions About Crystal Oscillator Stability

Posted by Bliley Technologies on Feb 27, 2018 6:30:00 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...

7 Incredibly Effective Ways to Prevent Pressure Transducer Problems

Posted by Rob Rutkowski on Feb 19, 2018 8:28:00 AM

Poor manufacturing environments can significantly reduce the performance quality of a pressure transducer. A failing pressure transducer will lead to problems with sensors and will provide inaccurate readings (or none at all).

A faulty pressure transducer not only can cause frustration and wasted time, but can also lead to unnecessary costs.

To prevent pressure transducer problems or failure from happening in the first place, let's take a look at 7 pressure transducer troubleshooting methods to keep your transducers & sensors working great!

How Well Do You Know RADAR?

Posted by Bliley Technologies on Jan 2, 2018 6:30:00 AM

When radar was first used in combat, it represented what is known as a “Revolution in Military Affairs” (RMA), a term used to describe a tactical, doctrinal, strategic, or in this case, technological change in military theory and activity that fundamentally changes the nature of warfare. World War II saw the first widespread use of radar on both sides of a conflict, and led to the emergence of electronic warfare as a method of counteracting the other side’s radar abilities while defending the friendly use of the electromagnetic spectrum. This competition spawned the evolution of many different radar functions for specialized applications. This article will explore various types of radar systems that exist and the functions they serve.

The Impact of RF Engineers on the Commercial Space Industry

Posted by Bliley Technologies on Nov 28, 2017 6:30:00 AM

 

While the expansion of the private sector into space is still in its infancy, there is little doubt that it will prove to be one of the most significant economic developments of this century, and RF engineers are one group of industry specialists that are making it happen. Indeed, it's almost impossible to overstate the impact that engineers specializing in radio frequency tech have had and will continue to have, not only with operating and maintaining commercial space activity but shaping it as well. Let’s explore all the different ways that RF engineers are making the “Space 2.0” era possible.

The Evolution & History of Radio Wave Technology [Infographic]

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

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.
