RF Circulators for Microwave Signal Routing

Our RF Circulators and Isolators are designed to protect sensitive components and manage signal flow with high precision in high-power environments. These components provide the necessary isolation to prevent reflected power from damaging transmitters, making them essential for radar, cellular base stations, and satellite communications. Engineered for low insertion loss and maximum power handling, our circulators ensure your system maintains peak signal integrity even under high VSWR conditions.

Choosing the Right Circulator/Isolator

When selecting a Circulator or Isolator, the primary metrics are Isolation and Insertion Loss. These determine how effectively the device protects your hardware while maintaining signal strength.
Other critical factors include: Power Handling: The maximum forward and reverse power the device can safely manage without degradation. Bandwidth: Ensuring consistent performance across the specific frequency range of your application. Operating Temperature: Critical for maintaining magnetic stability and performance in harsh outdoor or aerospace environments.

Circulators Technical Questions and Answers

What is the difference between a circulator and an isolator?
A circulator is a three-port device where signals travel in one direction (Port 1 to 2, 2 to 3, etc.). An isolator is a circulator with the third port terminated, allowing power to flow in only one direction and absorbing reflections to protect the source.
High VSWR indicates significant reflected power. Our circulators are designed to steer this reflected power away from your sensitive transmitter stages, ensuring system longevity even in mismatched antenna conditions.
Isolation is the measure of signal attenuation in the reverse direction. It is typically expressed in dB and is calculated as the ratio of the input power to the leaked reverse power:$$Isolation (dB) = 10 \log_{10}\left(\frac{P_{in}}{P_{leak}}\right).
