Inside Frequency Control

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

Before we dive into the differences between the 5 GNSS constellations... It's important that we're all on the same page with the difference between GNSS and GPS.

Many people get GNSS and GPS technology confused. A good way to think about the Global Navigation Satellite Systems (GNSS) is as the backbone (or underlying technology) behind GPS. The Global Positioning System (GPS) GPS is a GNSS constellation, but GNSS is not always GPS. GPS is one of the 5 GNSS constellations used around the world.

The 5 GNSS constellations include GPS (US), QZSS (Japan), BEIDOU (China), GALILEO (EU), and GLONASS (Russia). We'll cover each of these constellations in-depth in this post.

I have a feeling you're in need of some new test equipment... a new signal generator to be exact. If so, you've come to the right place. Maybe your current signal generator is outdated. Or maybe you're looking for your first one (in which case we'd be honored). 

No matter the reason, we wanted to share with you the best selection of waveform signal generators on the market today to help you make the best purchase based on your needs.

According to Statista,  there is a projected 30 billion Internet of Things (IoT) devices to be connected by 2020. That would be over a 400% increase in connected IoT devices from 2014. Most of these IoT devices will need to be connected through at least one type of wireless radio frequency (RF) communication.

Quartz crystal oscillators are the high and mighty option for low phase noise and added frequency stability in circuit design. Yes, simple oscillators like those made with resistor-capacitor (RC) or inductor-capacitor (IC) resonators are fine for some circuits. But if you're dealing with higher performance applications in aerospace, military, and space industries... you're going to want a higher performance crystal oscillator that can maintain low phase noise & strong stability. Otherwise, you'll risk deviating from the very specific (and many times critical) center frequency selected for your design.

The harsh truth is, selecting the wrong quartz crystal oscillator can quickly kill any design. With the wide variety of options and specs available in the market today, selecting the perfect crystal oscillator for your design can be a difficult and time consuming task.

One of the key things you need to know before purchasing a crystal oscillator is expected costs. There are multiple ways and specifications that can quickly drive up (and down) the costs of OCXOs and other crystal oscillators. In this post, you'll learn the top 8 cost drivers for crystal oscillators in order of most influential to least influential.

By the end of this post you'll have a much better idea of where to focus your cost-cutting efforts and to save the most in the long-term. Much of it just depends on your specific application and needs and where you're able to be more flexible.

Note: Oscillator pricing is very dependent on your specific needs and application. Be sure to contact us for specific information and pricing based on your needs.

With the recent start of the new space revolution and the rapid growth of Low Earth Orbit (LEO) constellation technology in recent years, there have been tons of questions being asked as to what all these new LEO satellite innovations and technologies are all about.

The LEO industry is skyrocketing with many new groundbreaking opportunities arising as new technologies are developed. Some even refer to this growth as the fourth industrial revolution. We're already seeing major players arise in this industry such as SpaceX, OneWeb, and Blue Origin. These are currently among the top companies in a race to bring the internet to the entire globe via Low Earth Orbit satellites.

In this post, we're going to answer:

• What exactly is the purpose of these large LEO constellations?
• Why are so many satellites needed?
• How are LEO satellites different from traditional satellites?
• Which frequency bands will these constellations operate on?
• Who are the current major players in this space? (No pun intended)

Trust me, you’re going to want to know ALL of the answers with so much talk happening right now around this topic.

Have you noticed how difficult it seems to find transparent pricing for frequency control & crystal oscillator components? If so, you're not wrong. Traditionally, it has been difficult to find quick, standard pricing for all things frequency control. Instead, you're basically forced to go through the long quoting process to even get an idea of expected pricing. So why is this? In this post I'm going to explain why OCXO oscillator pricing has been traditionally hard to find, and how Bliley's innovative pricing approach will make your procurement process so much easier.

Also, be sure to check out our OCXO immediate pricing guide at the end of this post!

The world is officially hyped to get their hands on new 5G technology. In fact, there was a recent spike in excitement when Verizon announced the release of the first 5G compatible phone, Moto z3.

However, there is still a long way to go until 5G networks are available nationwide. As we get closer to that point, new timing and sync problems are arising.

Let's take a look at some of these foreseen timing challenges that are coming with the implementation of 5G networks. Then, we'll cover some possible solutions to these problems.
