Hi, in the relation with RF module, is there any TX-booster (5-10 Watt) for some RF-module?
because I need to design one to multipoint data acquisition in long range.
I'm already have TRF-24G (nordic chipset, 2.4GHz ISM band, GFSK modulation) but its hard to find 2,4GHz booster when I gogling it.  Maybe anyone here know it, or the alternative 433MHz complete solution (RF module + booster)?

Thanks.

The magnitude of the power you are looking as 5 -10W is excesivly big. What is the distance you intend to reach. Commercial transmission amplifiers are in the same region.
If you could obtain say 50 - 100mW and direct them to your receiver you could obtain 10  20 miles with ease.

Check for application sites for motorola or philippes. Sure you will find sometiing suitable to boost your nordic.

Direct and LOS (line of sight) is not the answer because its "one to multipoint" in neighborhood environment, the receiver is in portable thing. So the big TX power is to compensate the obstacle between (high building, walls). I'm search for module, have no time to design.  Actually I  had been use 7W booster (but has ended the contract with the supplier) so I have seen the range they reached.

What was the cost of PA as contract and the cost if you were to buy one. Trying to find a solution for you if the alternative is cheaper than yours.
By the way which country is your location. Rgds.
