High Power Waveguide Circulator / Isolator
High Power Waveguide Circulator / IsolatorAchieves small size and low loss as a microwave power supply system component. Both 3-port circulator and 4-port circulator are possible. In addition to the general Below Resonance design, it is also compatible with Above Resonance for higher power.
- Megawatt class high power circulator / isolator
- Compatible with 4-port high-power circulators
- Cooling method supports water cooling and forced air cooling
-
High Power Rotary Joint
High Power Rotary JointRotary Joint for High power of several ten megawatts which enable power loss to be stable by mode converting round to rectangular waveguide or rectangular to round one.
- MW High Power, Low loss
-
High Power Dummy Load
High Power Dummy LoadThe dry load can prevent water from entering the waveguide. Water load has a structure capable of absorbing a microwave, and can achieve stable VSWR even when high power is supplied.
- Mega Watt L band to X band
- Low VSWR
