UHF power amplifier design [hlp]

hello
how we can design a UHF 600Watt power amplifier system for TV broadcasting using 150Watt power amplifier modules?

simply use 4 port power combiner dividers , so u combine 4 150 watt PA's to get the 600 W

what's about other components in the system? for example control unit?

the control unit , can be coupled by directional coupler , and then use a power detector to check the output power level , this unit should be at the output of the PA

hello khouly
can you introduce any experienced block diagram?

it will be like the block diagram in ur other post

Instead of power combiners I prefer hybrid couplers.
