An uncommon catalog
of original and interesting
a Windows® electrical filter design and analysis program
handling all of the usual options (family, topology, bandwidth, etc.).
It has a very nice toolbox including real-time tuning modes, Monte
Carlo, optimization and much
more! Printed outputs are
a Windows® meterscale drawing program
to allow you to
design and print professional-quality meter scales on your printer.
Nice options include the ability to import a graphic (and resize and
place it where you want), make a modern-looking "flattened" scale, use
seriff or sans-serif fonts of any size and specify the scale colors.
a specialized Windows® a filter design and analysis
designed to expedite the design of lowpass and highpass
filters using S
a specialized Windows® filter design and analysis program
designed for the serious radio amateur to expedite the design and
analysis of optimized amateur-band transmitter output lowpass
a Windows® program to help you design and analyze
helical-resonator bandpass filters
, usually used in the VHF and
UHF frequency ranges.
a Windows® program to allow you to design and analyze PI-L
a Windows® program to allow you to design and analyze diplexer
This Windows® program replaces the classic paper version of
the Smith Chart
. The load end of a network can be specified
regarding the R and jX values, up to five elements from the component
library can then be installed between the load and the generator. Then
going to the analysis page allows tuning or editing the network values
to achieve a match, in the usual manner. The complete system can be
saved (and later recalled).
an interactive Windows® program to allow you to design and
analyze active allpass networks
used for single-sideband signal
generation. Accepts orders from two to ten, specified operating
frequency range and analysis frequency range. Reveals sideband
suppression, chain angles and angle differences. The program has a
component-tuning mode. Arbitrary components may be used, or nearest 1%
or 5% values and results seen. Writes LTspice file.
an interactive Windows® program to allow you to design RF
amplifiers using the single-ended Class E topology
