RF Link Budget Calculator
Received power from transmit power, antenna gains, cable losses, frequency, and distance using free space path loss. Values in dBm and dB.
Link Budget
Calculate received signal power accounting for transmit power, antenna gains, cable losses, and free space path loss. All power values in dBm, gains/losses in dB.
