Having some problems with a class C amplifier. Well not so much the amplifier just the 'tank' part of it in the collector. I need to calculate the bandwidth of this circuit, it comprises of a 50mH inductor in parallel with a 0.22uf capacitor. Please note that there is no resistance in the circuit. The equations have been for the Q factor which is needed to be able to calculate the bandwidth.All the equations I have come across use resistance in the calculation but this circuit doesn't have any. So this circuit is LC and not LCR like you would normally see.

Someone please help. I 've looked in tons of books and can find no examples.

Thanks

Matt
