Quarter wavelength rf
WebBecause of the wave-like nature, the wavelength (lambda) dictates the spatial periodicity of the wave with a period of lambda. Using the ratio of voltage and current quantities at point x you can find the impedance which is also spatially periodic with lambda/2. The quarter wavelength and half wavelength cases are just special cases of interest. WebRF Module Design and Validation Co-Op. Skyworks Solutions, Inc. Jan 2024 - Dec 20241 year.
