Ok. I understand. This looks good. Would you know a good supplier for a
GPS antenna with LNA and filtering ? Approximately, how much would this
product would cost ?

Hi Alexander,
This looks good. Thank you very much.
Could you please send me the datasheets ? It seems you forgot to attanch
the files.
I will meet the French fab next monday. I am quite optimistic. This
company looks really serious and prices seems to be reasonable.
They would need some information about the TI160808U601 and the
TI201209U121. Could you please let me know a supplier for these beads ? Do
you have an approximate idea of the price of these components ?
Datasheets of two suppliers (manuf) attached here.
Actualy in Russia TECSTAR company more popular, but I can't find their
datasheet.
Aprox price - $0.05 @ reel qty
By the way, if it is not already included in the
GPS chip, it might be
useful to add a 1575 MHz GPS SAW filter on the GPS Rx path. As we will
transmit a strong GSM Tx signal, it might saturate the GPS Rx if we place
the GPS antenna near the GSM antenna. What do you think ?
Usualy active GPS antennas already contain LNA and filtering.
More over, DC bypass will be required if we put SAW filter at input.
Best regards.
Jean-Samuel.
