Radio frequency diplexers (RF diplexers), which are three-port frequency-dependent components used to separate or combine signals, are critical components in most radio systems. The three terminals comprise the RX and TX filters and a common port. As signals go through the common port, frequency directs them.

If you want to buy RF diplexers for your business needs, don't simply consider the diplexers price, but also keep the package style in mind. Choices for diplexers packaging include:

1. Surface mount technology (SMT), which is a package type used in products such as RF diplexers, where the component leads mount to the top surface of a circuit board.

2. Through hole technology (THT), a package type similar to the SMT. THT is sturdier and a bit more complex, since pins hold the components together in the RF diplexers until soldering.

3. A flat pack has flat leads on the RF diplexers on either two or four sides.

Action Steps
The best contacts and resources to help you get it done

Purchase products from a dependable RF diplexer manufacturer

Look for RF diplexers that stand out among others because of military and commercial functions. Make sure the diplexers come from certified manufacturers that put them through rigorous testing before selling.

I recommend: KR Electronics provides products for military and commercial use, including wireless applications. It prides itself in design, testing and keeping customers satisfied. Sage Labs has a wide selection of RF components, including RF diplexers. It provides components for commercial, space and defense markets.

Order custom RF diplexers to fulfill your product needs

While most manufacturers carry a product in stock that you can use, you may find that custom RF diplexers fit your needs better. An RF diplexer distributor may work with businesses that have unique radio frequency specifications.

I recommend: Myers Engineering International (MEI) is a licensed, professional engineering firm that specializes in producing radio communication systems. It works with clients to develop custom designs then develops and manufactures the product. Dorado supplies a wide range of RF diplexers for clients worldwide.

Consult with an expert to garner information about RF diplexers for optimal product performance

Sit down and consult with a RF diplexer supplier about specifications and expectations regarding your RF diplexers purchase. When you look for a RF diplexer to buy, don't shop at just any RF diplexer store--make sure the supplier offers support for the product.

I recommend: Tusa Consulting Services (TCS) works with clients to develop solutions for land and mobile radio communications. It has over 25 years of experience in the industry, including 13 years working with public safety. Intota offers a listing of experts and consultants for magnetron information. Its experts cover areas from microwave development to materials.
