I am basically working on dual band GSM jammer,i.e; GSM 900 & GSM 1800.
But in RF section i am not able to find VCO ICs.
CVCO55BE; this is for GSM 1800. The output frequency is 1785-1900 MHz and the output
power is up to 5 dBm.
CVCO55CL; this is for GSM 900. The output frequency is 925-970 MHz and the output
power is up to 8 dBm.

If I get these ICs from an old Cell Phone,,will jammer work properly..
becoz VCO used in cell phone is for Uplink but i want VCO for downlink frequency.


Plz help.
