Inside Frequency Control

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 can not only cause frustration and waste time, but it 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 seven pressure transducer troubleshooting methods to keep your transducers and sensors working great!

There are many different types of crystal oscillators. OCXOs, TCXOs, and VCXOs are some of the most common types of oscillators. Each have their own advantages and disadvantages. One of the core responsibilities of a lead RF engineer is to pick the oscillators that are an optimal fit for their designs and applications.

If you want to be able to fine-tune your frequency source and get a stable, dependable signal, a voltage-controlled crystal oscillator (VCXO) might be just the solution you’re looking for. Let’s explore the benefits of the VCXO and how you can put them to work in your designs.

Do you know all about atomic clocks in space and how they work? If not, it's about TIME you do. (Haha. Ha. Ha...)

Timing is everything when it comes to GPS satellites and other space applications. Even just a one-microsecond error in timing can lead to an error of 300 meters on the ground. Because atomic clocks can maintain very precise timing, they're a great solution for GPS and other LEO satellites.

There are 7 key factors to understanding successful crystal oscillator circuit design. These include:

1. Series circuit
2. Crystal load capacitance
3. Parallel circuit
4. Drive level
5. Frequency vs. mode
6. Design considerations
7. Negative resistance

GPS disciplined oscillators (GPSDO) are some of today's most trusted and accurate sources of timing. These powerful devices (sometimes called GPS clocks) consist of a high-quality stable oscillator and a GPS receiver. The GPSDO works by disciplining (or steering) the oscillator output to a GPS device or GNSS satellite signal via a tracking loop.

Surface acoustic wave (SAW) filters offer a reduced size, weight, and cost compared to other filter technologies. There are many tradeoffs, however, that need to be considered when selecting a SAW filter for your system design.

What are SAW filters? What are some common SAW filter applications? How are SAW filters used for mobile communications? We'll answer these questions and more in this post.

We'll be honest, crystal oscillators aren't the easiest topic to understand. That's mostly because there's a wide variety of crystal oscillator types that do different things, in different ways, for different purposes. This is largely due to their almost endless applications. From satellite communications in space, to military & defense, to telecom and more... there are so many different needs for crystal oscillators. 

In this post, we'll cover the most common types of crystal oscillators, which include:

• Oven controlled crystal oscillators (OCXO)
• Temperature compensated oscillators (TCXO)
• Voltage controlled oscillators (VCXO)
• Clock oscillators (XO)
• And some other key types within these categories

I know it sounds like a lot to cover, but don't worry! We're about to make things a whole lot easier for you. By the end of this post, you'll learn the basic uses, advantages, and limitations of each crystal oscillator type.

Virtually all electronic components benefit from mass production. As it turns out, it’s harder to benefit from buying a few parts compared to buying many. This is true for the production and ordering of Oven-Controlled Crystal Oscillators (OCXOs). There are several important advantages to buying these in bulk instead of in small quantities, including lower setup costs, shorter lead times, and reduced impact of supply chain issues. 

We’re often asked if it’s wise to purchase crystal oscillators in large batches, especially when commodity managers are aware all the oscillators might not be used right away. 

By nature, crystal oscillators are made of natural quartz material, which gives them a very long shelf life. In this article, we’ll take a look at why that is and how the stability of crystal oscillators gives them an indefinite shelf life.
