As a crucial microwave/millimeter wave device in modern communication systems, directional couplers play an essential role in power distribution of signals within a certain frequency range according to a certain ratio. They can also be used for power synthesis, signal sampling and detection, and have isolation functions. Its performance is mainly measured by indicators such as operating frequency band, directionality, standing wave ratio, coupling degree, insertion loss, etc.

Characteristics:

The dual directional broadwall coupler belongs to a type of coupler, which has the characteristics of high directionality, dual orientation, small standing wave of the main waveguide, and high power tolerance.

Classification：

The dual directional broadwall coupler is divided into two product types: dual directional broadwall coupler and double ridged dual directional broadwall coupler.
1. The connector type of waveguide dual directional broadwall coupler is waveguide port, with various specifications such as WR-19, WR-42, WR-75, WR-137, etc; There are various types of coupling ports such as 2.92mm, SMA, WR-90, etc; The power ranges from 0.016MW to 0.79MW.
2. The power of the dual ridged waveguide high directional dual directional coupler is 2000W, and there are several types of waveguide ports such as WRD180 and WRD750; The coupling ports include 2.92mm, SMA, N, etc.

Application:

The waveguide dual directional broadwall coupler is widely used in microwave measurement, sampling, high-power detection, microwave feeding systems, radar, communication, navigation, satellite communication and other equipment. In the waveguide reflection measurement of scalar network analyzers and vector network analyzers, this series of products are used as reflection sampling devices to avoid human and systematic errors during calibration and measurement processes.

Qualwave supplies broadband and high power Dual Directional Broadwall Couplers in a wide range from 5GHz to 59.6GHz. The couplers are widely used in many applications.
