Dual Directional Loop Couplers, Frequency Range Of 8.2~12.5GHz (Supporting 20% Bandwidth), WR-90 (BJ100) Interface

The waveguide dual directional loop coupler is a microwave component with the following uses and characteristics:

Purpose:
1. Power monitoring and distribution: The waveguide dual directional loop coupler can couple the power in the main line to the secondary line for power distribution and monitoring.
2. Signal sampling and injection: It can be used to sample or inject signals into the main line signal, facilitating signal analysis and processing.
3. Microwave measurement: In microwave measurement, waveguide dual directional loop couplers can be used to measure parameters such as reflection coefficient and power.

Characteristic:
1. High directionality: The waveguide dual directional loop coupler has high directionality, which can effectively isolate forward and reverse signals and reduce signal leakage.
2. Low insertion loss: Its insertion loss is small, and its impact on the transmission of mainline signals is minimal.
3. High power capacity: The waveguide structure can carry a large amount of power and is suitable for high-power microwave transmission.
4. Good standing wave ratio: The main waveguide has a small standing wave, which can ensure the stability and reliability of signal transmission.
5. Broadband characteristics: The waveguide dual directional loop coupler typically has a wide operating frequency band, which can meet applications in various frequency ranges.
6. Compact structure: adopting waveguide structure, relatively small volume, easy to integrat.
