Link budget free space loss

Nettet31. okt. 2024 · To calculate free space path loss for isotropic antennas, follow the given instructions: Take the square of the wavelength of the carrier wave. Multiply the distance between the transmitter and receiver antennas by 4π, and take the square of the result. Divide the value from step 1 with that of step 2. Congrats! Nettetvalues of the link parameters not given are as follows: Distance between the transmit and receive antenna = d = 40,000 km The free space loss (FSL) at 4 GHz according to Equation (13) is: [FSL] = 20logf + 20logd + 92.44 The satellite output power (20 W) in decibel is: [Pt]=10log10Pt= 10log10 20 = 13.0 dBw
