Auctus AT1846S Question
Posted: Tue Oct 12, 2021 5:11 am
Hello,
I am hoping to get a little more information on the Auctus AT1846S specifically, its use in low cost DMR radios such as the GD77. The most common low cost DMR radios seem to share very similar design utilising an MCU such as a STM32 or NXP, a blackbox Baseband IC from "HongRui?" and the AT1846S.
My main question is, what role does the AT1846S play in the digital signal path?
Is the I/Q output from the HR_C6000 piped into it for transmission?
Mic --> HR_C6000 -- > AT1846S --> Preamp --> Power Amp -->>> Airwaves?
Or is the AT1846S only used to receive the digital signals and transmission is done differently?
I understand this may not be a relevant topic of discussion and if so, please let me know and I'll delete the thread. Either way, I look forward to hear you all.
Cheers,
Alex
