High Power Coaxial Circulator is a crucial component in RF and microwave systems, specifically designed to handle high power levels while providing efficient signal routing and isolation within a coaxial transmission line.

Product Details

Characteristics and Applications

Its robust construction and reliable performance ensure efficient signal transmission and safeguard sensitive components from potential damage caused by high power levels. The High Power Coaxial Circulator is commonly used in high-power communication systems, radar systems, and other applications where high power handling capability is essential. With a focus on high-quality materials and precision engineering, this circulator delivers exceptional performance and reliability in demanding high-power RF and microwave applications.

Key Features & Advantages

1. High Power Capacity:
   • High Peak Power: Can withstand pulse powers from tens of kilowatts to several megawatts, suitable for radar systems.
   • High Average Power: Can handle continuous wave power from hundreds of watts to several kilowatts, suitable for broadcasting, communication base stations, and industrial heating systems.
2. Low Insertion Loss:This means minimal energy loss for the forward transmitted signal, significantly improving overall system efficiency and reducing energy waste and heat generation.
3. High Isolation:High isolation effectively prevents reflected signals from returning to the source, providing crucial protection for core active devices (such as power amplifiers).
4. High Stability & Reliability:
   • eatures a fully sealed structure, offering good resistance to moisture, salt spray, and mold.
   • Wide operating temperature range (e.g., -55°C to +85°C), ensuring stable performance in harsh environments.
   • Excellent power tolerance and long-life design ensure long-term, stable system operation.
5. Excellent Voltage Standing Wave Ratio (VSWR):Low VSWR (typically < 1.5) ensures good matching with transmission lines, reduces signal reflections, and guarantees signal integrity.

Typical Applications

• Radar Systems: Connects the transmitter and antenna. During transmission, it directs high-power pulses to the antenna; during reception, it directs weak echo signals to the receiver while isolating the transmit pulse, protecting sensitive receiver circuits. It is a core component of the T/R Switch.
• Mobile Communication Base Stations: Positioned between the Power Amplifier (PA) and the antenna. It directs the amplified signal to the antenna for transmission and directs the signal received by the antenna to the Low-Noise Amplifier (LNA), while isolating reflected signals to prevent PA damage due to mismatch.
• Broadcast Transmitter Systems (FM/TV): Used in power combining systems to combine the outputs of multiple amplifiers and isolate reflected power, ensuring transmitter stability and efficiency.
• Industrial Heating & Medical Equipment: Used in microwave energy applications such as microwave ovens, plasma generators, and medical MRI systems, protecting the source or amplifier from load variations.
• Scientific Research: Used in high-power experimental setups like particle accelerators, NMR, and plasma research.
