right Power amplifier
hi
y GSM PA ? can i use AMPS power amp bcoz some one tell me that amsp PA more powerful then GSM . and the funcation of PA is same
can i cover 2 story buliding with jammer 1 by using 2 antenna

Why not?
>>can i use AMPS power amp...and the function of PA is same ?
There is nothing to it.
Do you know the NIKE slogan? Just do it.
>>...some one tell me that amsp PA more powerful then GSM
Although I don´t know the absolute tx power of AMPS and D-AMPS, I estaminate D-AMPS has a similar tx power to GSM.
Maybe AMPS is stronger (because it´s analog).
>>can i cover 2 story buliding with jammer 1 by using 2 antenna
No. You must use two jammers.

hi
friend plesae see my circuit and tell me y the range is just 10 metter ,s only what u want me to change in this ....
its PA from GSM phone ( what if i remove these three resistors ) and what if i tune the gain
and this is part of input signal swooth gen from jammer one and DC offset from richy the great .
plesae tell me how to improve the range in this case
Hi,
10 meters are not so bad for the beginning.
What about a real gsm antenna, not just a simple wire?

i use old GSM phone antenna but did work well... give me a idea what type of antenna should i use and where can i find it and see the circuit i am thinking to remove the three resistors ( which are before PA) what do u think
good work !
so far ...
what's our amplifier current?
Chris
ohohoohooooo.... after detailed looking
short the way --> VCO ,attenuator ,amplifier ...
may there's RF feedback from the antenna ...
try looking ...
hi thx,s for reply,s
well the PA input 5V
so u want me to place the parts near to the VCO (right)
what about antenna ....and idea
