When RF signals pass through an isolator, they experience less loss than they would if they were passing through other types of components. By using RF isolators, the signals from one system can be prevented from entering the other system, thus reducing the risk of interference and improving the overall performance of both systems.Īnother advantage of RF isolators is that they can be used to improve the efficiency of RF systems. One of the main advantages of using RF isolators is that they help to prevent interference between different RF systems. RF isolators are devices that are used in radio frequency (RF) systems to prevent the transmission of RF signals in one direction while allowing them to pass in the opposite direction. We can manufacture RF Isolators to meet any frequency range and power requirement that your project has. Our RF isolators come in a variety of connector series including SMA isolators, type N isolators, 2.92 isolators, SSMA isolators, drop in isolators and more. Konnect RF manufactures a complete line of RF isolators. Most of our RF and microwave circulators are RoHS and REACH compliant. Our line of RF circulators have frequency capabilities over 500 GHz. Konnect RF 50 Ohm RF circulators and isolators are available with a variety of different series connectors such as SMA circulators, N circulators, 2.92mm circulators, TNC circulators and more. Ferrite circulators are typically used in microwave ovens, cell phones, and satellite communications. The ferrite core creates a magnetic field that causes a phase shift in the RF energy as it passes through the device. They are made of a ferrite core material that is surrounded by a coil of wire. The most common types are ferrite circulators and waveguide circulators.įerrite circulators are the most widely used type of RF circulator. There are several types of RF circulators, each with their own unique characteristics and applications. This phase shift allows the energy to be directed in a specific direction, while blocking energy from flowing in the opposite direction. It does this by using a non-reciprocal component, such as a magnet, to create a phase shift in the RF energy as it passes through the device. The basic function of an RF circulator is to direct RF energy in a specific direction. They are often used in telecommunications systems, such as in microwave ovens, cell phones, and satellite communications. See Mix Selection for other applications.įor extra large cables use the FB400-31 which has an inside diameter of 3 inches (76mm).Konnect RF- RF circulators are devices that are used to control the flow of RF (radio frequency) energy in a circuit. Use Mix 61 for VHF and above for RFI/EMI suppression and below 30 Mhz for multi-ratio impedance transformers (baluns/ununs). USE FB102-31 for 4 turns of RG-8X for 16X increase in Z per bead – see pictures below for examples). If you need more Z, just use more beads in series on the cable or use more windings thru a larger ID bead (e.g. Mix 31 has better response below 10 Mhz but above 10 Mhz mix 31 and mix 43 are very close. For 500 ohms we would need 5 mix 31 beads or 6 mix 43 beads to have greater than 500 ohms. For example if you have a 50 ohm RG-8 coax cable and want a choking impedance of 500 ohms at 10 Mhz, you can check the FB102 column (since FB102 will pass RG-8 through its center ID) at 10Mhz and find that Mix 31 has a Z of 108 ohms/bead and Mix 43 has a Z of 91 ohms/bead. Application Note: Use impedances for each bead at your desired frequency to select number of beads needed for desired Z.
