CommsLink - RF & Microwave

CommsLink calculates the power transfer of a line-of-sight communication link. The program uses the Friis Transmission Formula to calculate the power received at the output terminal of the receiving antenna. It assumes the antennas are pointed at each other for maximum gain and that there are no impedance mismatches at antenna terminals. Also the transmit and receive antennas have identical polarisations and are aligned for polarisation match.

To calculate the power transfer, simply enter the transmit frequency, transmit power, antenna gains and distance between antennas and the received power will be automatically calculated.
