We are happy to inform you that QuickFil 5.1 is now freeware.
Passive Filter Design - QuickFil
QuickFil is a software for designing passive electronic filters. The result is an optimized circuit of inductors (L) and capacitors (C).
Types of Filters
- Asymmetric bandpass filters
- Parametric bandpass filters
- Butterworth (maximally-flat filters)
- Chebyshev (equal-ripple filter)
- Inverse Chebyshev
- Elliptic (Cauer)
- Bessel (maximally flat delay)
- Modified Bessel
- General Equal-ripple approximation
- General maximum-flat approximation
|You can design filters up to 50th order.||All limits are of practical nature.|
|The inputs are automatically checked in order to avoid program errors which are common in this field.||While you are inputing your specifications, QuickFil shows you the consequences and checks if the inputs are feasible (Timesaver).|
|Dependent fields are updated automatically on line.||You can optimize the specifications of the filter and find a trade-off between the theoretical and the practical world.|
|Circuit topologies and values may be changed or reordered. Reverse, dual and two-port manipulations are available.||You can choose the best topology concerning the mechanical limits of the filter.|
|Variations in the filters are also possible using Norton/Impedance transformation and Pi-to-Tee conversions.||This feature can be used to optimize your components. You will get better and cheaper components (saves money).|
|The filter can be analyzed including losses (component quality Q).|
You can estimate the minimum quality of the filter components.
|You define different terminating resistors.||This feature can be used for matching networks.|
QuickFil runs on:
Windows 95, Windows 98, Windows ME, Windows NT, Windows 2000, Windows XP and with a small workaround also on Windows Vista, Windows 7 and Windows 10.
|QuickFil is the fastest passive filter design software on the market.|
|QuickFil is very easy to use.|
|QuickFil helps you reduce the production|
cost of the filter
|QuickFil helps you design filter of a higher quality.|
