we have some issues for the design for the SR4G053

I am trying to use the SR4G053 for our L1+L5 antenna application. I have seen your reference design is different to our reference design with the GNSS module. I am not sure which one to follow. We may need some support from your side. Is it active antenna or the passive antenna?

the reference antenna design from the GNSS module provider is shown below, not same as your reference design

Hi Liuluan,

Our SR4G053 antenna is a passive antenna.  We would be happy to work with you on your reference design.  Please contact to start a discussion in regards to placing the antenna on your PCB and tuning recommendations.

Best regards,

Geoff S.

Hi liuluan002,

Raptor is a passive antenna. The circuit recommended by the module vendor is a pi network which is always the minimum standard topology recommended. However, we recommend an extra component, please us the recommended topology from our data sheet.

We are happy to help you through your design process right from the start, please contact to get in touch with your regional representative. 

Many Thanks
