TRF371125: Front End for GNSS

Gerald

Part Number: TRF371125

Hi Experts,

Our customer is interested in Front End for GNSS. He need RF receiver with downconverting mixer and amplifier and ADC in order to acquire GNSS (GPS) signal.

I have referred our customer to this link below:
Global positioning system receiver design resources | TI.com

Customer said that the link was useful but he need RF Front End in one chip. For example do you have device as integrated component like on the next figure?

He checked but not sure if TRF371125 could be used as GNSS front end with digital output. He need device with digital output which will be used as input for software defined receiver (on PC).

We hope to receive your advise on this. Thank you.

Kind regards,

Gerald

Hi Gerald,

The WI team here has AFE76xx, AFE77xx, and AFE79xx that can serve as integrated front end with digital output. However, these are high performance devices meant for base station setup, and are way overkill for GPS. You can try products in the EP team. I will move you

Hey Gerald,

I'm aware of a solution which combines a SimpleLink MCU with a CC4000 GPS module (see SWRA584) but this part is now obsolete. The customer will need to find a third-parts GPS module front-end.

Ryan
