Meet Production Volume While Controlling Costs and Risk
Using filters with higher ripple deviation than specified introduces distortions that can result in wireless devices incorrectly sending or receiving data. Ripple deviation is a key filter specification that helps prevent signal distortion in the filter passband. A network analyzer measures the reflection and transmission characteristics of the filter, also known as the S-parameter. Regular calibration of the network analyzer reduces many systematic errors in the test, ensuring that the results are as accurate as possible.
