this program expedites the design of lumped-element diplexers using both the lowpass/highpass and the bandpass/bandstop topologies.
here are the highlights of this program:
this interactive program accepts for its inputs the crossover frequency (for the highpass/lowpass topology) or the lower and upper bandedges (for the bandpass/bandstop topology), the order (number of parts), the passband ripple and the system impedance.
click on the design button and you see the schematic drawn on the screen including component values.
click on the print button and send the data plot and the schematic to the printer using a very high resolution plotting system (not just a screen dump).
on the plot screen, you can "tune" the cossover or bandedge frequencies, the passband ripple and the order and get instant feedback regarding how those items affect the transmission to the two ports as well as the return loss looking into the common port.
on exiting the program the current design is saved to enable a simplified program restart.
