Antenna Interface
MV31-W also provides connectivity for off board antennas. The antennas and their connection
interface for this device satisfy the requirements specified in
. The antenna elements are typ-
ically integrated into the notebook/ultra book /tablet and connected to MV31-W via flexible RF
coaxial cables. MV31-W provides four RF connectors (MHF4 type). The four RF connectors
include for 5GNR Sub 6G & UMTS/LTE primary transmitter/receiver port, diversity receiver and
4x4 MIMO receiver port. For the location of the antenna connectors see
.
For LTE and 5GNR Sub 6G to ensure stable RF performance, customer must assemble ade-
quate antenna according to the antenna specification.
Note:
•
Antenna peak gain limit as 2.5dBi for frequency <1.5GHz and 4dBi for frequency >1.5GHz
of module level certification
•
For Japan regional peak gain should be limited as 2.5dBi for frequency <1.5GHz and 3dBi
for frequency >1.5GHz
•
For Band 30 peak gain limit as 2.99dBi (meet FCC requirement)
•
For Band 48 peak gain limit as 0.92dBi (meet FCC requirement)
