power rf amplifier schematic request

I need the schematic of Power amplifier in class AB form at 20 MHZ in narrow band.

Thanks in advance.

Here are some application notes from Motorola on RF power design.

Transistor power amplifiers are usually broad band type because of the danger of damaging them if driven into a reactive load such as outisde the tuning range of a narrow band network. You can follow one of these amplifirs by a band pass filter if you need it.

Hi
You can find your request in this paper .

regard

too few information...
output power?

The output power is 1 Watt for 50 mili volt at input..
must first habe pre amplifier with 200 gains(23 db)_ at narrow band.
if you design with 2n2219 & 2n2905 its good for him!
is this information alot ?
thanks in advance
