A Link Budget puts into account all gains and losses a signal goes through in a system as it is transmitted. The calculator calculates the power of the received signal given amplifier and antenna gains, and medium loss.
This balanced attenuator calculator helps you determine the resistor (R1) values for a balanced attenuator.
Given three of the four input parameters (refractive indices, angles of incidence, and refraction) this tool calculates the missing variable based on Snell's law.
A helpful tool for computing the Effective Isotropic Radiated Power (EIRP) of an antenna
This tool is designed to calculate the maximum distance (range) that a radar can detect
