Microwave Isolator is a passive, non-reciprocal device with three or more ports used to transmit microwave energy in a specific direction. This Microwave Isolator is used to prevent reflected microwave energy from the magnetron preventing excessive magnetron heating or molding. Microwave Isolator is a circulator with an absorbing load, attaching to the port used to transmit the reflected energy that is generated from the magnetron and is transmitted to the load port and absorbed. This Telecommunication Equipment is widely used in telecommunication, test equipment, electronic warfare, radar and avionic systems. This broadcasting equipment is available in various frequency ranges and multi-junction topographies requiring diverse applications. They are configured with diverse features for various applications like drop-in or coaxial connectorized packaging, for pc board or cable installation in pcs/pcn and cellular based stations, and for point to point microwave radio telecommunication links.
