- Coax Cable Calculator
Returns the Impedance (Ohms), Cutoff Frequency (MHz), Capacitance (picofarad), and Inductance (picohenry) when provided with the Dielectric Outer Diameter (in.), Inner Conductor Diameter (in.), Dialectric Constant. - Decibels for Voltage or Power Ratio
The routine asks for what type of ratio, Voltage or Power. It then asks for the values of that ratio. It then calculates the decibels for that ratio. - ERP and EIRP Calculations
Both ERP and EIRP can be calculated if the power of the transmitter is known in watts and the db gain of the antenna is known. Once ERP is known and either P or A is known, this routine can calculate the unknown P from A or the unknown A from P. - Free Space Path Loss
Provide the frequency of the transmission in MHz and the distance either in miles or kilometers, and the routine will return the path loss and the path loss in dB. - Frequency From Wavelength
Provide the wavelength for a signal in meters and the routine will return the frequency of the signal in MHz. - Inductive and Capacitive Reactance Calculator
Calculates the missing variable when provided any two variables required for determining Inductive Reactance or Capacitive Reactance. - Narrowband Balun
Calculates the inductance and capacitance for a given frequency (MHz) and two impedances (Ohms). - Ohm’s Law
Calculates the missing value from the Ohm’s Law variables V, I, R. - Ohm’s Law Full Solutions
Solves for all 12 Ohm’s Law formulae depending on the variables provided. - Resistor or Capacitor in a Parallel or Series Circuit
Provided with the type of circuit, the value of each resistor or capacitor, the routine returns the total capacitance or resistance for that circuit. - Skin Depth Calculator
Based on Frequency, Resistivity, and Relative Permeability, the skin depth in μmeters and μinches is returned. - VSWR Calculator
Returns the VSWR and associated statistics given the power forward and power reflected in watts. - Wavelength from Frequency
Provide a frequency in MHz and the routine will return the wavelength in meters and in feet and inches.
