Affordable Microwave Isolator
Introduction to RF Isolators
Any microwave equipment necessarily must employ RF isolators for preventing unwanted signals from interfering with the output of the transmitter. As microwave isolator of fact, isolators are vitally important for safeguarding RF components against high-level currents and signal reflection. Isolators are in great demand, as we need to have many receivers and transmitters at many locations. The geographical conditions play a substantial role, causing interference in the transmission of data and voice.

Ferrite materials are used for manufacturing RF isolators. They are able to identify the direction of the flow of current entering these devices and dissipate or trap it accordingly. Needless to say, there are various manufactures producing this kind of items, but you should be careful in choosing the one that produces goods that offer top class performance.

Here are the primary specifications of an RF isolator:

Frequency (MHz): That is the operating frequency of the device. Look for isolators having a high frequency band. Depending on your specifications, get isolators offering a variety of 0.8 GHz to 26 GHz.

Isolation (dB): The minimum degree of isolation from the output port to the input port. Usually this will be minimum 16 dB, although isolators rated for 20 dB may also be available.

Insertion Loss (dB): This represents the loss of signal from the input to the output port. Ideally it must be as low as possible.

Power (W): Two forms of power come into play here. The forward power refers to the amount of power that the isolator can carry from the input to the output, while the reverse power represents the number of power that the isolator is designed to carry from the output to the input.


You will have to select an isolator that conforms to the RoHS and REACH standards. You may choose to use SMA or N connectors, depending on specifications of one's product.

Certain requirements of RF isolators, together with the related products, are going up each day, as our day to day lives at workplace and otherwise are becoming increasingly influenced by wireless systems. That is why there is a large number of companies manufacturing these items. You may import them. Although prices may show large variations between different manufactures, it is recommended to use a reliable and reputed manufacturer, to get quality products.

It is essential that you procure your RF isolators and the related products, such as a coaxial circulator, from a highly reputed and reliable source that has been in this business for some time. In fact, you should choose a vendor that can produce these items according to your specifications. The producer also needs to be able to deliver the items in accordance with your schedule.
