RF Design utilities
RF Filter design
AADE Filter Design V4.5 Design and analyse passive filters in both the frequency and time domain.
RFSim99 by Stewart Hyde RF simulation with S-parameters. Not only for filters.
RFSim99 is freeware software that helps with impedance matching and can simulate RF circuits. Plots Amplitude and phase response, different display styles including Smith chart. Uses one and two-port Scattering parameters. You can for example import an S-parameter file of your filter from your network analyser and have the software calculate matching. Requires Windows 95, 98, NT or 2000 (WinXP virtual machine runs it just fine)
