Lumped to Distributed

You can replace a lumped element such as an inductor or a capacitor with a distributed stub element. The replacement will be made by approximating the response of the lumped and distributed sections around at a given frequency and given physical length. The frequency (fo) and length are obtained from filter specifications and are usually the best choices. However you can change these in the Transformation Settings dialog box.

This transformation is not an exact-equivalent operation. The filter response is optimized at fo, but it will be distorted for other frequencies.

 

To replace a lumped element with a distributed element:

1. Select a lumped element such as inductor, capacitor or an LC-resonator.

2. Click Lumped to Distributed on the Filter>Transform submenu. If the frequency fo is not suitable for the operation, you will be asked to enter another value for the frequency of application.
