Input (grid or cathode) and output (plate) tube resistances
calculation according to its electrical characteristics, frequency, mechanical
dimensions and working conditions.
MS Excel worksheet
Inductance calculation for single layer, air-wounded coils and helixes up to about 800
MHz. Inductance calculations accuracy is around 1%.
Also, coils with maximum Q for given inductance, resonant RF chokes,
PI and T resistive attenuators calculations are provided. Skin effects, radiation losses
and other minor side effects are not accounted in maksimum
Q factor coils calculations. Program assumes using copper (Cu) enameled or silver
(Ag) plated wire. Program is writen bilingual in English
and Serbian.
MS DOS programs:
Inductance calculation program for air-wounded coils and helixes up to about 800
MHz. Inductance calculations accuracy is around 2%. Skin effects, radiation losses
and other minor side effects are not accounted in Q factor calculations. Program assumes using copper (Cu) enameled or silver plated wire.
Program for calculations of HP, LP and BP filters at VHF and UHF frequencies
up to about 800 MHz.
This program calculates geometry, gain, losses, efficiency, directivity
pattern and other parameters of primary fed and offset parabolic antennas.
Calculate Az-El position of geostationary satellites at specific location and carrier to noise ratio of received SAT TV signal.
Calculate impedance matching networks.
Program calculates dimensions of log-periodic antennas.
This program calculates impedance matching for tube and solid-state PA, LNA,
antenna match-box, interstage impedance matching and all other impedance matching
in electronic and telecommunication.
Warning: Using of this program assumes
knowledge and experience in
constructions and projects. Program will always give some calculation results,
but how it will work in practice, and even whether will work at all, depends completely on user of the program, and so responsibility is
always on him.
