Introduction
Every decibel of loss counts when your transmitter pushes hundreds or thousands of watts. A customized high power RF circulator keeps energy flowing forward and safely routes reflected power to the proper port. For radar, satellite links, and industrial RF chains, this is the difference between stability and stress. At HzBeat, we build tailor-made ferrite circulators that merge reliability, compactness, and miniaturization.
What Defines a High Power RF Circulator?
A true high power circulator is engineered for thermal robustness, magnetic uniformity, and low loss. Core design elements include:
- Advanced ferrite: high Curie temp, low loss tangent.
- Efficient heat spreading: in drop-in or waveguide housings.
- Low insertion loss: <0.25 dB typical and high isolation >20 dB.
- Wideband impedance matching: across L/S/C/X/Ku/Ka.

Why Customization Matters
No two high-power systems are identical. HzBeat customizes by combining 3D EM simulation, magnetic analysis, and thermal modeling:
- Target band + power (10 W → 2 kW CW; pulsed on request).
- Form factor: microstrip, drop-in, coaxial, waveguide.
- Thermal pathway + magnetic uniformity optimization.
- VSWR balance and system-level impedance tuning.
