Is the circuit around GNSS of nRF9160 DK 0.8.5 reliable?

[Yusuke]

According to the blog below, hardware design of nRF9160-SICA has been fixed on May 31st.

I'm designing GNSS-relate circuit which is connected to nRF9160 and need a reference for it.

Is it Ok to design a circuit referring to nRF9160 DK 0.8.5?

Isn't there any design update in the GNSS related circuit of the next version of nRF9160 DK?

If so, I will imitate the nRF9160 DK 0.8.5; nRF9160(GNSS port) - LNA - RF switch - GNSS antenna
I'll use BGA524N6E6327XTSA1 for LNA. This doesn't have a filter.

Also, I'll use SKY13522-644LF for RF switch

I know that software update will be required to let GNSS function perform fully.

Any advice and suggestions are welcome.

Thanks.

Hi Kaja,

Is it necessary to use RF switch between LNA and Antenna? I want to use an onchip GPS antenna on my custom board.

if yes, then why we need to use it?

Thank you,
