A basic of the clasic means tuned resonant amplifier used very widely in high frequency amps to boost voltage gain. Output of this type of amp can be much higher than supply voltage. To boost selectivity a frequently this amp is associated by "Q multiplier" circuit . This is a coil quality factor multiplier.

I noticed that as I played around with coils and caps on it, I think I might make an 800MHz CDMA amplifier out of one of these, or multiple of them! Hahahaha evil scientist! :p

Oh yes this can be good choice for 800Mhz amp if u chose a right transistor. Inductor should be aircored wired on wisely selected case to avoid selfcapacitance multiplication. Remember that many crazy behavior might arise at such frequencies and u will have problems to direct watch of output wave on scope screen due to too high frequency far beyond most scopes capability beign typically around 100Mhz

A varactor amplifiers are more user friendly at suh frequencies. Parametrical amplfication is almost noiselss and almost completely resistant to external distortions . And parametrical oscilltors and frequency converters are most stable structures that can be build frequently break of parameteical oscillations can only be achieved by removing power source or physically removing crucial element fom circuit.

How many parts roughly should a decent cell phone amp need Sec?

I prefer to get amped with MDMA. Hey-O!
