ZTS offers a wide variety of circulators to fit customers requirements. These unique devices enable two signals to use one channel. The classic use of this three port device is for the line/coax between an antenna and a transceiver, allowing the receive signal to come from the antenna (port 1) to the receiver (port 2) while the transmit signal goes from the transmitter (port 3) to the antenna (port 1). An isolator can be created by terminating one port into a matched load. These components can be used in antenna transmitting and receiving, radar, amplifier systems and anything that requires isolation from a signal reflection and the ability to send signals in opposite directions down a single channel. Our circulators feature excellent low insertion loss, high isolation and reliability.

ZTS offers a wide variety of isolators to fit customers requirements. These are two-port devices that transmit microwave or radio frequency power in one direction only and block the signal in the opposite direction. They can be thought of as a diode for RF energy. Isolators are used to isolate equipment from the effects of conditions outside of the equipment. For instance they are used to prevent a microwave source being detuned by a mismatched load. Our isolators feature excellent insertion loss, high isolation and reliability.

Circulator & Isolator Applications: Radar systems; Telecom Infrastructure; Microwave Radio Systems; Military; Communications Systems; Wireless Radio Systems; R&D Labs etc;
