Hi Alexander,

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.

Please let me know.

Best regards.

Jean-Samuel.

Best regards,

Andrey Sviyazov.
