What is EIRP ? Discuss the importance of G/T ratio. Calculate overall C/N for a satellite link if : C/N uplink = 25db , downlink = 20db and Intermodulation = 12db.

Effective isotropic radiated power (EIRP) is defined as an equivalent transmit power and is given as

$EIRP = Pt Gt$

Where $Pt = \text{transmitted power}$

$Gt = \text{transmit antenna gain}$

Express as log

$EIRP(dBW)=Pt(dBW) + Gt(dB)$

In respect to transmitter output

$EIRP = Pt - B0 - Lf + Gt$ …
