Hi, Gurus,
In Bosch mmwave radar FCC-ID report on MRRevo14F NF3, its freq band is 76-77GHz.
But in Bosch datasheet on 3QF, with the same ID, i.e. MRRevo14F, it syas the antenna gain is 23dBi.
There is 2 TX antennas in 3QF, I guess one is for far field with 76-77G, and the other is for near field with 77-81G.
But there is no 77-81GHz info on the FCC report.
I checked ITU-R standard on 76-81G, and it says 77-81G antenna gain is 23dBi.
So I guess 3QF should use 77-81G for near field, although there is no 77-81G info in FCC report.
Maybe the report is earlier than the 77-81G standard, or 77-81G is free license?
Right?
Attachment R-REC... is the ITU standard.
Attachment en_302264... is the ETSI standard.
Attachement MRRevo14F is the radar spec.
And the antennas picture.
Best,
Tony Liu
