Power amplifier at high frequency

[Luckyboydtt]

I am looking for a chip which can amplify power supply at high frequency (from 400-500MHz). Can you help me? Thanks

I don't think you'll find a chip amp to go that far.

Nothing I can think of will do that. It would not be called an audio chip if it could.

The devices, power transistors,
that can give very high power at high frequencies ( 400-500MHz )
are some rare Radio Transmitter Transistors.

They are used for Radio Broadcast.
They are very, very expensive.
I would not think there are special high power RF chips.

Thanks for their advices. Do you have the detail cuircuit of this. I means the circuit is created by single elements such as : trans,...

There are RF power modules available for various frequency bands and power levels. Mitsubishi make a range. VHF modules are available up to about 30W output, UHF modules tend to be lower power up to about 10W.
Ebay quite often has them.
Beyond this, you will have to make something which is way OTT for this forum.

Thanks. Can you give its name?

What kind of power output are you looking for?

[Luckyboydtt]

power 6W. Can you give a detail circuit for it.

Hi,
there are RF amplifier chips used to boost aerial signals before reaching the tuner input.
I think they work from 100MHz to 500MHz.
