It is used to protect your RF components from excessive power reflection, such as preventing a microwave source from being detuned by a mismatched load. With a quality termination attached (having a VSWR of about 1.05:1 or better) isolation of 24-26 dB can be achieved for narrowband units, and 15-20 dB can typically be achieved for broadband units.įor further reading, see the in depth explanation by Kevin Obyrne of Ditom:įor design and distribution support, please contact Powell. An RF isolator is a 2-port device that transmits microwave or radio frequency power in one direction only while blocking the signal in the opposite direction. Isolation is dependent on two things primarily: the quality of the termination on the isolator, and the VSWR of port 3 on the isolator. When matched well to the isolator, this element will dissipate any energy it encounters as heat, stopping it in its tracks. This termination has an element inside its shell called the load element. Description: 6600 to 7100 MHz, 20 dB, Low Power Drop-In Isolator. An isolator has isolation because a termination is attached to port 3 of the device, not a connector. RF & Microwave Isolator from M2 Global Technology. Isolation is a measure of how well an isolator can carry out its main purpose of decoupling energy entering port 2 from whatever is attached to port 1. This behavior heavily attenuates any signal entering port 2 before it reaches port 1, yet allows almost all of a signal entering port 1 to reach port 2. Any energy that enters port 2 will be routed to the matched termination on port 3, and quickly dissipated as heat. Energy can only enter port 1 and travel to port 2. The device has only 2 ports, and as a result, has only one path for energy to flow without significant attenuation. Model-C122I Isolator, supports 5.4-5.9 GHzĬontact To know Circulator manufacturers, pl.This article is extracted from information written by Kevin Obyrne of Ditom.Īn RF isolator can be thought of as a diode for RF energy (See diagram above).Īn isolator is simply a circulator with one of its ports terminated with a matched 50Ω load.
