#WHAT IS A HARMONIC BLUETOOTH#

Various radio technologies typically operate at different radio frequencies (RF) - Bluetooth operates at 2.4 GHz (gigahertz), Wi-Fi at either 2.4 or 5 GHz, GPS is typically 1575.42 MHz (megahertz), and cellular devices can operate at many different frequencies in the range of 700 MHz to 2.6 GHz depending on your region, cell phone carrier, and device support.įor purposes of this discussion, from here on in we will focus on Bluetooth Low Energy (BLE) radios and their operational frequency of 2.4 GHz or wavelength of approximately 5 inches. These devices all achieve wireless communication by exploiting the electromagnetic (EM) radiation properties of electrical conductors described by good ol’ James Clerk Maxwell:

You’ve never heard of any of these in your life and are just knowledge hungry - don’t worry, we’ll cover the basics of harmonics and BLE so you’ll walk away satiated.īluetooth devices among other electronics utilizing technologies such as Wi-Fi, cellular, and GPS all communicate wirelessly.

Harmonic emissions have ever given you nightmares at some point for a BLE product you were developing.

You’ve heard the term “harmonic”, “spurious” or “emissions” thrown around in the electronics industry and are wondering what that’s about.

How are harmonics generated and how can they be mitigated? A little more technical.

Harmonics Part 2 - Determining the Source of the Harmonic

What are spurious harmonic emissions and why can they be bad? Back to the basics.

Here’s an overview of the topics that will be covered in each post of the two-part series: Harmonics Part 1 (this part) - Introduction to Harmonics & BLE Identifying future challenges and knowing where to get help is a critical path to success, and Punch Through is here to help!

This blog post aims to help you better understand what harmonics are, where they come from, how they relate to Bluetooth Low Energy (BLE), and how to make them go away so you can get back to dreaming about rainbows and unicorns while your product is making you $dough$. Welcome to the first part of a two-part blog brought to you by the Punch Through Team! We hope this two-parter helps educate readers on a topic at which Punch Through excels.
