Bluetooth technology is now over 20 years old and is one of the global standards of connection. Bluetooth is used in various leading communication technologies, including point-to-point, broadcast and mesh communication topologies. 

A large percentage of the world's communication chipset manufacturers, including Qualcomm and Nordic-Semiconductor, utilise either Bluetooth Low Energy (Bluetooth LE) or Bluetooth Basic rate/enhanced data rate for data transfer.  

Due to how valuable and essential these Bluetooth chipsets are, Golledge Electronics are proud to be able to provide approved crystal solutions for pairing with these chipsets. 

Our advanced crystals for Bluetooth pairing come in a wide range of circuit conditions and standard frequencies, including 12.0MHz, 16.0Mhz, 26.0MHz and 32.0MHz. Shop below to find the best crystal recommendation for your Bluetooth device.

What frequency is Bluetooth?

As a leading supplier of Frequency Control Products, we are well-versed in the technical specifications of various wireless communication technologies. As Bluetooth has developed rapidly over the last 20 years, we have continuously updated our knowledge, skills and services to reflect its importance.

Bluetooth is a wireless technology that operates in the unlicensed Industrial, Scientific, and Medical (ISM) band at 2.4 GHz. Specifically, Bluetooth uses a frequency hopping spread spectrum (FHSS) technique that hops between 79 different 1 MHz-wide channels within this band to avoid interference with other wireless technologies.

This frequency range offers a good balance between range, power consumption, and data transfer speed, making it an ideal choice for short-range wireless communications in consumer electronics and industrial applications. At Golledge, we offer a range of high-quality quartz crystal oscillators and other frequency control products that can be used in Bluetooth applications to ensure stable and accurate frequency operation.

The components of a Bluetooth circuit

Our range of crystals recommended for Bluetooth pairing are available with ultra-miniature packages and in a wide range of circuit conditions and standard frequencies including 12.0MHz, 16.0Mhz, 26.0MHz and 32.0MHz.
