Can any one help me for the schematic or some site for reference guidelines. Will be greatful for.

Crystal, LC resonator or perhaps ceramic? What is the required frequency stability with time/temperature? power amp: required linearity (what does "sinewave" mean in terms of harmonic suppression in dBc), required efficiency? Work those specs!
