SMA Circulators

Pasternack SMA Circulators are passive 3-port microwave devices that control the signal direction and flow within the RF circuit. Similar to isolators, circulators are made of ferrite materials and magnets that determine the directional flow of the signal. These circulators offer minimum isolation between 16dB and 20dB, 50Ω impedance, and frequency capabilities ranging from 1GHz to 26.5GHz, depending on type and style. Pasternack SMA Circulators can be utilized in antenna transmitting and receiving, radar, and amplifier systems, as well as any application that requires isolation from signal reflection and the ability to send signals in opposite directions down a single channel.
