Southwest Antennas offers coaxial isolators and circulators for use in RF systems. These devices are used to direct the flow of RF energy through a system in one direction and prevent unwanted damage to sensitive components. Circulators generally feature three or more RF ports, with each port directing input RF energy to the next port in sequence, such as from port 1 to 2, and from 2 to 3, and 3 back to 1. Isolators have two RF ports and direct the flow of RF energy in one direction only and prevent it from reflecting back through previous components in the RF chain.
