Lowpass filter uses only two values

Posted on Oct 5, 2012

The composite lowpass filter uses interior constant-k full sections terminated by m-derived half-sections.The design technique is also applicable to highpass and wideband filters (references 3 and 4). Figure 1 shows a schematic of the composite lowpass filter. The filter uses four inductors of two different values and five capacitors of two different values. Figure 2 shows the schematic of an equivalent composite lowpass filter. This filter uses judicious combinations of components in series, parallel, and series-parallel. The filter uses eight inductors and 14 capacitors of only one value each.
