Pengiraan Belanjawan Pautatas
EIRP = 10 log
PT +
GT
dimana PT dan GT =
Untuk Antena bumi
= 10 log 7 + 12
= 20.4 dBW
L = 20 log S + 20 log
fU +
92.45
S = jarak satelit - bumi
= 20 log 650 + 20 log 0.440 GHz +
92.45
= 56.2 – 7.13 + 92.45
= 141.5 dB
C/T = EIRPT – L + GR/TR
= 20.4 – 141.5 + 0/270
= -121.1 dBW/K
C/kT = C/T + 228.6
= -121.1 + 228.6
= 107.5 dBHz
Pengiraan
Belanjawan Pautbawah
EIRP = 10 log Ps + Gs
dimana Ps dan Gs = antena satelit
= 10 log 1.5 + 16
= 17.76 dBW
L = 20 log S + 20 log fd
+ 92.45
fd = frek. pautbawah
= 56.2 - 16.7 + 92.45
= 131.9 dB
C/T = EIRP – L + G/T
G dan T adalah dari antena bumi
= 17.76 – 131.9 + 7/30
= -114 dBW/K
C/kT = C/T + 228.6
= 114.6 dBHz
C/N = C/kT – 10 log B
= 150 – 13.5
= 101 dB
