RADAR 101

[fa icon="calendar'] Jul 25, 2017 6:30:00 AM / by Bliley Technologies posted in RF, RF Engineering

[fa icon="comment"] 3 Comments

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.

2 Major Problems TCXOs Solve With Quartz Oscillators

[fa icon="calendar'] Jul 18, 2017 6:30:00 AM / by Bliley Technologies posted in TCXO

RF engineers are always trying to improve the performance of the systems they work on. A perfect, 100% stable signal which never deviates from the intended frequency will probably never be attainable in reality; the toll that the physical environment and time will take on a crystal remains a fact of life.

But that doesn’t stop us from always working towards getting as close to possible to that ideal. Both of these challenges can be mitigated by selecting a high-quality oscillator. Picking the right one for the job depends on the application for which it is being used, as well as other factors like the amount of power available.

In this article, we will make the case that for those who are trying to minimize the effects of aging and improve stability without using a lot of power, a temperature-compensated crystal oscillator (TCXO) might be the right solution.

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.

How to Maintain Frequency Stability in Crystal Oscillators (Plus FREE Checklist)

[fa icon="calendar'] Jun 27, 2017 6:30:00 AM / by Bliley Technologies posted in OCXO, crystal oscillators, TCXO

[fa icon="comment"] 1 Comment

One of the core challenges any RF engineer faces is maintaining frequency stability in crystal oscillators. In an ideal world, an oscillator would transmit at the desired frequency indefinitely and without deviation…but of course, we don’t live in an ideal world, and frequency drift is a real problem in many applications. There are a number of factors which can cause an oscillator to deviate from the correct frequency, but it is not an insurmountable issue, and there are various approaches engineers can take to improve stability. In this article, we will discuss approaches to maintaining a high degree of stability in crystal oscillators.

What Cost Drivers Impact Oscillator Pricing?

[fa icon="calendar'] Jun 20, 2017 6:30:00 AM / by Bliley Technologies posted in crystal oscillators

[fa icon="comment"] 0 Comments

Oscillators have become an indispensable technology in the modern world. They are the core component that makes RF engineering possible, which in turn is what enables everything from cell phones to Wi-Fi to GPS. The modern, interconnected economy and life as we understand and experience it every day would grind to a halt if crystal oscillators were not abundant, well designed, and reasonably affordable. But what determines oscillator pricing?
