Motorola

Here are some application notes from Motorola on RF power design.
http://www.communication-concepts.com/application_notes.htm
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.
