Transmission Line Calc2.0 - App Store
You'll be able to see results in few seconds.
Publisher Description
Transmission Line Calc allows you to perform several calculations related to RF transmission lines.
After selecting from one of 53 different transmission lines, you specify the length and operating frequency. The characteristic impedance and velocity factor of the cable is displayed, and the attenuation (loss) as well as electrical length (in wavelengths and degrees) is displayed.
Next, you can specify the impedance (both resistive and reactive) and whether this is measured at the input to the transmission line or the load. The impedance at the other end of the transmission line is calculated, as well as the SWR (Standing Wave Ratio) for both ends.
The loss due to the SWR is then calculated and displayed, as well as the total loss.
Next, you can enter in the input power, the loss due to the cable as well as SWR is displayed, and the net power out.
