Impedance matching is one of the most critical aspects of RF design, and its complexity grows significantly in wideband systems used in modern communications. This course provides a structured way through the fundamentals of RF impedance, mismatch phenomena, and the quantitative metrics used to evaluate performance. Learners will explore classical single-frequency matching techniques before progressing to broadband solutions like binomial and Tschebyscheff transformers. The final section focuses on wideband impedance matching challenges in antenna arrays and practical system design trade-offs for minimizing loss. Designed for RF engineers and technical professionals, the course blends theoretical aspects with modern real-world examples, enabling participants to apply RF impedance matching strategies confidently in systems as 5G, Wi-Fi, and other wideband networks.

There are 3 modules in this course
This module lays the groundwork by defining impedance in RF microwave wideband systems, including complex and characteristic impedance, with a focus on its role in antennas and circuits for effective system design. It then goes into key metrics like reflection coefficient, return loss, and VSWR, demonstrating their quantification through tools like the Smith Chart to highlight the need for matching networks in power transfer. Finally, it examines the consequences of mismatch in wideband systems, such as reduced efficiency and reliability, emphasizing low VSWR requirements in arrays to prepare learners for practical RF challenges.

Frequently asked questions
To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
When you purchase a Certificate you get access to all course materials, including graded assignments. Upon completing the course, your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
