Radio frequency couplers (RF couplers) combine coupling signals in an asymmetrical manner in order to sample radio frequency transmissions. Select your RF directional couplers and basic RF couplers by considering performance specifications such as frequency range, reflected power and return loss.
When purchasing RF couplers for your business, keep in mind that there are three basic types of this device:
1. The unidirectional RF coupler design consists of a four-port device with main and output lines, a coupled line and output and a fourth port with internal termination, which isolates the coupled output from the main output.
2. Bidirectional RF couplers are a lot like the unidirectional couplers; however, there is no termination on the fourth port.
3. The RF directional coupler, also called the Dual directional, is a four-port device with two unidirectional couplers.
Action Steps
The best contacts and resources to help you get it done
Purchase dependable RF coupling devices
Whether you are looking for a RF directional coupler or RF hybrid coupler, look for couplers that stand out among others because of their reliability and design. Make sure the couplers come from certified manufacturers that put them through rigorous testing before selling.
I recommend: Whether you are looking for couplers for military or aerospace use, consider Herley. It works with the United States government and militaries worldwide to provide solutions and carries products like the Quadrature coupler. Radio Frequency Systems offers customers around the world a wide range of inventory, when it comes to radio system components. This ISO compliant company offers services and expertise on six continents.
Garner information about RF couplers by consulting with manufacturers
Manufacturers most likely have current information about RF couplers, including what designs are coming out soon. They can offer insight into what might best suit your purposes.
I recommend: Telewave offers customers many different types of radio system products. It has sales representatives all around the United States and a toll-free phone line for customers in North America. Emerson Network Power Connectivity Solutions offers products such as the "F" Inline Coupler. The company has over 80 years of service, selling numerous products from specified brand names to satisfied customers.
Have a manufacturer design a custom RF coupler for your equipment
Sit down and consult with a manufacturer about specifications and expectations regarding your RF coupler purchase. Look for companies that can design new products to meet your requirements.
I recommend: Myers Engineering International (MEI) is a licensed, professional engineering firm that specializes in producing radio communication systems. It often uses hybrid couplers, directional couplers and phasing couplers in its designs. Diversified Technologies helps clients cut costs and develops solutions through consultations and development. The company staffs experts in design, analysis concept generation and testing.
