PRX / DRX / RX2 / RX3 Physical Meaning

For the RM500Q series / RM502Q-AE each of the RSRP, RSRQ, SINR AT commands have PRX, DRX, RX2 and RX3 paths. Please could explain the meaning of PRX, DRX, RX2 and RX3?

RX2 and RX3 seem to not give valid responses.

I get answers like:
+QRSRP: -98,-96,-140,-140,LTE
+QRSRQ:-12,-13,0,0
+QSINR:16,15,0,0

hi,epwr:
Since RM500/RM502 supports multi-antenna (4T2R) MIMO
PRX: Primary RX
DRX: Diversity RX
RX2: MIMO-RX2
RX3: MIMO-RX3

Hi, Herbert,
is MIMO-RX2 the same as PRX MIMO and MIMO-RX3 corresponds to DRX MIMO? We are using the RM520N-GL Modem in 5G NR mode in band n78.
The RM520N-GL Hardware Design Manual (Pages 52, 53) doesn’t know RX2 and RX3 and I want to know the relation between Antenna connector and received signal.

  • ANT0: TX1/DRX
  • ANT1: PRX MIMO (=RX2?)
  • ANT2: TX0/PRX
  • ANT3: DRX MIMO (=RX3?)
    Thanks for clearification.

Please refer to page 30 “Antenna Interfaces for RG520F-NA/RG520N-NA”

Unfortunately can’t find the document in the download area. Can you please send me a link to the file.

I have sent it to your email,pls check

Sorry for the inconvenience, but this document (Quectel_RG50xQ_Series_Hardware_Design_V1.3.pdf) does not contain any information about the RM520N modem.

Sorry, I was careless. I resend it to you

Hello! Please send the technical documentation for the MiMo antenna system for RM520G

I have sent it to you

Hi Herbert

May I request a copy of this technical document for the MiMo antenna system for RM520G?

Thank you.

I have sent it to you,pls check,and I hope you can click the :yellow_heart: for me,thx
