PCfilter - RF/Microwave Design Software for Filters
​Where Synthesis enables Analysis™

Software Product: PCfilter - Parallel Coupled bandpass Filter

Atlanta RF Software offers RF/microwave CAE software product: PCfilter, which performs synthesis of the electrical circuit, synthesis of the dimensional circuit and frequency analysis of multi-section Parallel-Edge Coupled Bandpass Filters constructed in stripline or microstrip. Some product features:

1. Synthesis of multi-section Parallel Edge-Coupled Bandpass Filter designs:
   1. Synthesis of Electrical circuit: Zoe & Zoo for each section.
   2. Synthesis of the Distributed circuit: Line Widths (W) & Strip Spacing (S) for each resonant section of the filter.
2. Synthesis of various Filter Design Options:
   1. Chebyshev or Butterworth type frequency response.
   2. Construction in Stripline or in Microstrip.
   3. Prototype Lowpass Circuit Elements included.
3. Frequency Analysis response profile of:
   1. Input VSWR and Thru-path Insertion Loss.
   2. Higher-order TE11 modes.
4. Default values for each User-entered input data.
5. Output Data stored on your hard drive for graphical plots.

​Software product: PCfilter provides the User with full design capability, from Synthesis to Frequency Analysis of Parallel Edge-Coupled Bandpass Filters and their Distributed form, when constructed in stripline or in microstrip.
