Finding (and price also) POS 1060 from minicircuits is too hard.
I had also thought that I'll find POS VCO in mobile phones...Unfortunately...

I have broken S6 and PA is PF01414A...no datasheet available...

Ill try connect it with this simply circuit because I have no POS...

What do you think about http://perso.wanadoo.fr/jf.fourcadier/hyperfrequences/VCO/VCO.htm ?

Is there any chance to make its freq lower, in GSM band, changing varicap diodes or inductor?

Hi...

hmm, not easy to build , but possible.

...yes, you can make L1 a "little" bit bigger for lower frequencies, perhaps with the help of a frequency counter.

Really interesting site, I didn´t know it before... thank you.
I always wanted to build a vco for POS1060/MAX2623 replacement, too. This inspires



Another circuit (only in german, sorry)

Wow, I'm interested too...

Does anyone know what is the range of Mobile jammer V 1.0?

I think that VCO I suggest has enough output power to drive PA...
I'll try it after hollidays...
If someone make it, please, post opinions here...

Does anyone have data sheet for PA chip I mentioned above?

Unfortunately no datasheet for the PF01414A seems to be available nowhere, well, so i did some reverse engineering

Some presumptions of the PF01414A refer to the datasheet of the PF01411A.
http://home.vrweb.de/~josefkotte/PF01411A.pdf

No guarantee for nothing Any questions/comments?


@misley:
I´m really optimistic that your circuit and this power module will work fine together
[Besides, please don´t try to un-solder the PF01414A from the S6 board. It breaks quickly . Better use a saw, like i did it with the QCPM-9401 of my S4 Jammer. ]
