    The waveguide circulator is made of microwave ferrite material and is a linear non reciprocal device mainly used for unidirectional energy transmission in microwave systems. This unidirectional transmission performance is applied to the stages of microwave equipment, allowing them to work independently and be isolated from each other.

    The working principle of waveguide circulator is to utilize the Faraday rotation effect of the polarization plane rotating when electromagnetic waves are transmitted in a rotating ferrite material with an external DC magnetic field. Through appropriate design, the polarization plane of the electromagnetic wave is perpendicular to the grounded resistive plug during forward transmission, resulting in minimal attenuation. During reverse transmission, the polarization plane of the electromagnetic wave is parallel to the grounded resistive plug and is almost completely absorbed.

    Features:

    1. Small size: The volume of waveguide circulators is much smaller compared to traditional distributors and combiners, especially in the high-frequency range. This device has a very compact size and can be widely used in high-frequency electronic fields such as multi-channel communication and radar.

    2. Low loss: Due to the use of special waveguide structures and high-quality materials, waveguide circulators have very low losses in signal transmission, ensuring the quality of signal transmission. In contrast, in allocators and combiners, there is generally significant signal loss due to the need for signals to pass through multiple coupling points.

    3. High isolation level: The waveguide circulator uses waveguides of different frequencies to generate reverse propagation and mutual coupling in the ring region, which can separate signals of different frequencies. In high-frequency circuits, signal isolation and filtering are often required, and waveguide circulators can effectively achieve this function.

    4. Can be applied to multiple frequency ranges: The waveguide circulator has a certain degree of freedom in design and can be adjusted according to different frequency ranges. It can be applied to circuits in multiple different frequency ranges, and the versatility of this device is also one of the reasons for its wide application.

    Qualwave supplies broadband waveguide circulators in a broad range from 2 to 33GHz. The average power is up to 3500W. Our waveguide circulators are widely used in many areas.
