Inside Frequency Control

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.

Warning! EFC Over-Specification May Be Costing You (Do this instead!)

Posted by Rob Rutkowski on Oct 2, 2019 11:14:09 AM

What if I told you that specifying more Electronic Frequency Control (EFC) than you need could actually be hurting you pocketbook? Well, it very well may be! Paying attention to whether your supplier is using AT cut vs SC cut crystals will help you save money in the long run with OCXOs.

How are Robots Used in Space Exploration?

Posted by Bliley Technologies on Sep 10, 2019 8:22:00 AM

Historically, the role of robotics in space exploration has been significant due to the uninhabitable conditions of non-terrestrial planets in the solar system. According to AZO Robotics, a robot is defined as “a self-controlled device consisting of electronic, electrical or mechanical units that can function in place of a living agent.” In this post, you'll learn some basic history about robots in space exploration and 5 of the most popular robotics systems used in space history.

8 Common RF Engineering Problems That Impact RF Engineers

Posted by Bliley Technologies on Sep 5, 2019 8:22:00 AM

What's the best way to solve a problem? Preventing the problem from occurring in the first place (or knowing exactly how to tackle an inevitable problem whenever it occurs). In this post, we're going to cover 8 of the most common RF engineering problems that impact RF engineers on the regular. Making yourself more aware of these frequent RF engineering problems will allow you to be more prepared with a solution (or even prevent them from happening in the first place). Less problems = better engineering productivity & happier RF engineers!
