Frequency control / quartz crystals

Quartz crystals

Wireless applications often require highly reliable, low-power, frequency solutions in small form factors. We offer a leading range of leading-edge timing solutions from global leading suppliers – including, ACT, Taitien and Tai-Saw

This range covers:

  • High temperature and harsh environment crystals and oscillators
  • Small form factor
  • Compact SMD OCXO

Ideal for demanding applications, these ultra-small, ultra-low-power, surface-mount quartz crystal oscillators can be optimised for industrial applications and the special requirements of the automotive industry (AEC-Q200) and operate across an extended temperature range from -40 to 125°C.



Reducing radio frequency inference has enabled multiple wireless technologies to co-exist within a few millimetres of one another, therefore antenna efficiency, RF isolation and antenna selectivity are all critical considerations.

In many data-gathering and wearable IoT applications, compact designs mandate the use of an on-board antenna. These antennas can be chip, patch or PIFA antennas, or embedded into the PCB itself.

Many factors affect the performance of these types of antenna including ground planes, position of other components, orientation of the unit, materials used in the outer casing, and proximity to the outer casing.

We offer a wide range of antennas specifically developed for every wireless technology standard.

  • Cellular (2G, 3G, 4G and 5G)
  • Wi-Fi, Bluetooth
  • ISM bands including LoRaWAN™, SIGFOX and Zigbee
  • GNSS (including BeiDou, Galileo, GLONASS and GPS)
  • NB-IoT – LTE CAT-M1/NB1
  • Custom designs for non-standard frequencies

We can also support you with your designs

A poorly optimised or tuned antenna will have an adverse effect on the wireless range and power consumption of your design.

Access the latest RF antenna modelling tools, to help you determine the optimum antenna for your system and with our own in-house IoT and Wireless Communications Technology Centre, we can also design, specify and manage the production of custom solutions from ProAnt, to meet exact requirements.

Match, tune and measure antenna performance to get the best possible results and refine in an anechoic chamber, whether it features a standard, modified or fully customised solution and receive a full report on the matching circuits used, the performance and the radiation pattern of an individual product.



We offer a wide range of filters from some of the world’s leading manufacturers – including Tai-Saw, Johanson Technology and Sangshin – from surface mount through to custom mono-block - ensuring your signals are reliable, clean and precise, and noise is reduced to a minimum. 

Including band pass, high pass, low pass, SAW filters and duplexers for all types of IoT applications. These compact solutions are developed with easy RF design integration in mind to provide low-insertion and high-attenuation levels without compromising performance or cost.

Covering more than 700 designs for narrow and ultrawide bandwidths, frequency ranges from 500MHz to more than 6GHz. These solutions are available with extremely short sample and production lead times, are competitively priced and can be fully customised to meet you exact RF product requirements. AEC-Q200 automotive qualification is also available across many of our solutions.

Filter design service

We also offer a radio frequency filter design service through our Fibre Optics Technology Centre so you can delegate the form, fit and functional design responsibility to our experienced engineers allowing you to get on with the rest of your project. Design to your requirements with:

  • In-house design experts
  • Shorter development cycles – first article samples are typically available within a 4-6 week lead time.
  • Wide range of packaging – ensuring the most cost-effective filter design for the end environment.
  • Lower total cost of ownership – your custom filter solution is supplied complete, tested, certified and ready to install in your system, reducing assembly time and stock-control problems.
  • Reliability – all designs are manufactured in facilities accredited with ISO9001and fully tested to pre-agreed parameters, giving you complete confidence.

  • Available for all wireless standards

Enhance your wireless standards with a single easy-to-integrate, cost-effective, compact component by boosting the performance of your chosen SoC for a better user experience.


Shielding and thermal solutions

All wireless solutions use radio frequencies to communicate and transfer data and these frequencies interfere and impede the performance of other components within a design. Similarly, other components generate heat or interference, impacting the overall performance.

Shielding is typically applied to enclosures to isolate electrical devices from their surroundings, and to cables to isolate wires from the environment.

We cover an extensive choice of standard components through to high-quality products for electromagnetic shielding and heat dissipation from leading manufacturers.

Whether you are looking to manage heat within your design at the initial concept stage, or need to stop unwanted frequencies entering your design before entering production, we can offer solutions for any size or scale of project.

Protections covered for your design:

  • Fabric-over-foam gaskets
  • Board-level shields
  • Conductive foams
  • Elastomers and tapes
  • SMD contacts
  • Shielding clips
  • Custom solutions
  • Thermal conduction solutions
  • Metal contact strips for chassis shielding
