Re: SIMPLE Noise GENERATOR
12V
12V
too less voltage ...!!!!
for that VCO (POS1060)
Chris
now what should i do
hi
friend u drowing is good
can i have more rf spect plot . how to inceress in range of jammer
what is the rule of PA gain . is that use to tune the range
Let me sumarize.
So you have a working jammer but no PA yet.
Have a look at Kleiner Onkels jammer 1 again. He uses a QCPM-9401 for PA (which works really good) and a adjustable resistor to limit the gain, or better, the current.
The problem is that GSM PAs are not designed for continuous transmission like we need for a jammer.
In fact, in a mobile the PA transmits 0,5µs and then it pauses for 3,5µs! So the most of the time it´s off.
The long off-time has a special advantage: The PA has time to cool down after a short, powerful transmission.
Disadvantage for us: We want to transmit continously, and therefore we have to limit the current to prevent the PA from overheating.
This can be done with a adjustable resistor in the supply line.

so can u tell me what will be the best PA for the jammer......
>can u tell me what will be the best PA
No idea. What is the best car?
Collect some PAs from old mobile phones and then we will see which are suitable.
All non-SMD-PAs should be good.

any PA in ur mind
what about PF1040 .. what u use .
first think about a trashy phones ... than a constitute amplifier ...
Chris
so r u saying to tune gain i can get contiui.. apmlifer
