In numerous equipment, a switch-mode power supply (SMPS) delivers various output voltages, each powering different sections. With the introduction of low-voltage circuits such as DSPs, it's not ...

You would like to measure the input impedance of your circuit with a 50 ohm network analyze.r At the frequency you are interested in you measure a reflection coefficient of 0.8-j0.4. What is the ...

Q: The percent impedance of a transformer is also the voltage drop of the transformer at full load. What is the voltage drop of a transformer at various other load levels, i.e. 25%, 50%, 75% or in ...

A 50-Ω lossless transmission line is to be matched to a resistive load impedance with ZL = 100 Ω via a quarter-wave section as shown in the figure, thereby eliminating reflections along the feedline.

Dual-band impedance transformers and matching networks are pivotal components in modern high-frequency systems, facilitating efficient power transfer between disparate circuit elements by converting ...
