4 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 [3]. 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 Figure 1.
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)
