    How to go about making a Frequency Synthesizer for GSM ??

    Re: How to go about making a Frequency Synthesizer for GSM ? Thanks people..... Even i was thinking of the same thing, using a 6.4MHz Crystal. One more thing will a simple OPAMP (741) suffice for a loop filter. An active filter will be better rite !!!!!!!!!
