Impedance and Impedance Matching

Impedance measurement is important not only in passive components industry but also various industries such as materials, power supply, and so on. Physical parameters like capacitance (C), inductance (L) and resistance (R) are measured based on the impedance. Also, material parameters (permittivity: ε, permeability: μ) can be derived through impedance measurements. Keysight has a complete line of impedance test equipment and test accessories to help your measurement. When you choose an impedance measurement product from Keysight, you get more than accurate and reliable test results.

Impedance matching for optimal power transfer, noise and efficiency is routine in electronics, but designing impedance matching networks is always tedious. Matching frequency-dependent complex impedance over broadband is especially difficult. Fortunately, Keysight EEsof EDA has the broadest range of circuit synthesis and simulation software in the industry to help you tackle these problems that our engineers also face daily in the design of our test equipment. Over 70% of the world’s RF and microwave engineers use Keysight EDA design tools because they can repeatedly get it right the first time.

How to Match RF Impedance Effectively By Optimally Selecting SMT Devices 
This video demonstrates a very effective RF impedance matching methodology with SMT devices that helps RF engineers save time and cost. With this methodology, RF engineers can start to match the design with a list of good combinations of SMT devices which satisfies the target impedance and loss specifications instead of trying out unlimited possibilities at the workbench. This methodology should work very well with typical wireless or mobile product designs such as smart phones.
