High-Reliability RF Isolators & Circulators for Mission-Critical Performance
For more than 65 years, we’ve delivered precision RF isolators and circulators engineered for the most demanding environments.
Choose from proven standard products or custom-designed solutions, all designed, manufactured, and tested in the U.S. to meet exact performance and environmental requirements.
Coaxial circulators and isolators
Coaxial circulators and isolators are passive, non-reciprocal radio frequency (RF) devices that control the direction of signal flow in coaxial transmission systems. Designed for low insertion loss and high isolation, they are essential in radar, satellite communications and electronic warfare.
