RF & Noise Components Ltd. is a supplier of high performance Microwave and RF components specialising in isolators and circulators for the telecom, broadcast and military sectors.

While offering many industry standard products, our main advantage is our design capability and flexibility to meet customer requirements. Our circulator and isolator product range includes

  • Drop in
  • Surface mount
  • Coaxial
  • Also supplying high power coaxial terminations with heat-sink or as a cable assembly
  • ISO 9001:2000 Quality Policy

We can build to print, or redesign for form, fit and function as well as being able to cross reference many of the DML Microwave Ltd. products, offering equivalents to help support their legacy customers.

Coaxial Circulator

Having specialised in providing bespoke solutions for our customers we have managed to accumulate many circulator and isolator designs over the years for a number of different market sectors.

We have chosen a selection of these due to their popularity for our standard product range and can be supplied with additional options if required. Many customers have found it beneficial to have one or more of the following options:

  • integrated power monitors
  • phase matching
  • integrated heat-sink
Coaxial Circulator

Isohybrid

We can supply our isolators with a built in directive coupler. These isocouplers help reduce our customers overall costs and ensure the best performance is achieved by reducing matching problems between components. Other features can also be added to them including remote terminations and forward and reverse power monitors.

Drop in Circulator

We offer a range of drop-in circulators operating in the 300MHz to 4GHz frequency band. They can be supplied in one or more of the following package sizes. We also have a range of surface mount products, details available on request.

Drop in Isolator

We have a vast range of drop in isolators operating in the 300MHz to 4GHz frequency band. Depending on the operating frequency we have a number of profile options.

Typical parameters of a circulator and isolator.

  • Frequency range
  • Insertion loss
  • Isolation
  • Return loss
  • Forward power
  • Reverse Power
  • Operating temperature range
  • Storage temperature range

Surface Mount Circulator

We can also supply a surface mount option by including a PCB carrier to the base of the designs. Surface mount options are available for the main base station frequency bands and we can also supply bespoke solutions to meet other applications. Please contact our sales team with for more information.

Bespoke Designs

One of our key strengths is our willingness to provide customer spefic solutions whether it is for one piece or high volume production. Utilising our rapid development facilties we have been able to supply a new design based on a current mechanical profile on the same day it was requested. Naturally it only required a small amount of modification but highlights the speed of service we can provide.

For more complex designs where a number of new components are required we can typically turn around a new design in 2-6 weeks. The cost of designs requiring new components is kept to a minimum and we do our best to avoid NRE charges.

Our website only shows a selection of our commonly used products so even if you do not see something that meets your requirements please contact our sales team with the details and we will do our best to meet your needs.

Bespoke Designs

Prototypes and Samples

If you have visited some of our other web pages you will have realised that we have grown and prospered our business by providing products to meet each customers unique requirements. We understand that even if two or more customers are manufacturing similar products for the same market sector that their requirements may well differ and one solution does not fit all. With that in mind we have striven to provide prototypes and samples with the minimum expenditure. Most samples are provided with a 30 day return policy where we will give a full refund as long as the parts have not been damaged. Please note the refund does not include any shipping charges.

We also sell sample packs, an example of which can be seen in the picture to the right. For most products these can also be sold with a 30 day return policy but it must be requested and agreed in advance of order.

Prototypes and Samples

CAD - Modelling

RF & Noise Components utilise a 3D parametric solid modeling CAD package, which includes the ability to produce assemblies, parametric sketching and interference detection.

This enables us to rapidly generate new product concepts and minimise the design iterations between prototyping and the final manufactured part. Helping us to help you meet manufacturing deadlines.

Once we have the 3D model we have software to render the model using realistic materials to enable our customers to view what the final product will look like.
