The crystal oscillator purchasing process can be a headache if you don't know what to expect. However, learning the basics of procuring frequency control devices can help you to plan accordingly and decrease your frustration. We'll keep this one short and to the point.
5G Fixed Wireless Access (FWA) will be one of the earliest uses of 5G. 5G FWA will provide lightning fast gigabit internet speeds to homes, apartments, and businesses. Better yet, 5G FWA will be a fraction of the cost compared to traditional cable & fiber systems.
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 Maybe your current signal generator is outdated.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.
Drones have officially begun to constantly fly through the minds of society. The technology advances in flight technology, flight modes, and controls along with the advancements in portable photography and video technology have caused an explosion with amateur and professional photographers and videographers.

Welcome to the new world of CubeSat Manufacturers! These small satellites are becoming more and more popular in today’s new space industry. Their increasing popularity is mostly because of their small, lightweight, and inexpensive designs. The standard 1U Cube Satellite is 10cm x 10cm x 10cm in size. However, since their inception in 1999, new Cube Satellite companies have developed more variations in size to meet desired payload levels. A 1.5U, 2U, 3U, 6U, 8U, 12U etc. are now offered to meet customer's growing specifications.

The U.S Department of Homeland Security considers 13 of the nation’s 16 critical infrastructure sectors to be ‘critically dependent’ on PNT technology. Also, a loss of PNT would cost the U.S an estimated $10 BILLION a day. Not only do many everyday consumers use PNT & GPS on a daily basis, it's also crucial for military and intelligence operations. Other industries that strongly rely on GPS based PNT include
- Radio communications
- Network synchronization
- Intelligence systems
- Information gathering
- Cruise missiles
- Weapons systems
- Electronic warfare
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.
There are 7 key factors of understanding successful crystal oscillator circuit design. These include
- Series circuit
- Load Capacitance
- Parallel Circuit
- Drive Level
- Frequency vs mode
- Design Considerations
- Negative Resistance

Is it too early to start thinking about holiday gifts? Absolutely not! The holiday season is approaching quickly, so we wanted to help you start thinking through some great gift ideas for the engineers in your life (or soon to be). We also wanted to make this your not-so-average gift idea post that doesn't include your typical (boring) engineering mug or neck-tie gifts. Without further ado, here's 10 unique holiday gifts for engineers.
What if I told you that specifying more Electronic Frequency Control (EFC) than you need could actually be hurting your 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.
