Increased Power Handling Capability Pulsed Applications
GSM/PCN TDMA-Frame:
4,615ms
D = ^{t p} = ^0.577ms = 0.125
T
4.615ms
577µs
Take value ^{Ptot max} from diagram permissible pulse load
P_{tot DC}
--> ^Ptotmax
P_totDC
≈ 1.4
P_tot = 2W × 1.4 = 2.8W
DECT TDMA-Frame:
10ms
D = ^{t p} = ^10ms = 0.0417
T
4.615ms
417µs
Take value ^{Ptot max} from diagram permissible pulse load --> ^Ptotmax
P_{tot DC}
P_{tot DC}
≈ 1.5
P_tot = 2W × 1.5 = 3W
