Rf Specifications - Dejero EM9191 Hardware Integration Manual

3. RF Specifications

The EM9191 includes Four MHF4 RF connectors for use with host-supplied antennas, and eight
MHF7S connectors for use with up to four mmWave antenna modules (2 connectors per antenna
module):
Figure 3-1 Module Connectors Include Image with Spacing Info

Sub-6G/GNSS connectors:
 Main: Primary Tx/PRx path for 3G/4G/5G (except for n41)
 Auxiliary: Diversity Rx (except for n41) and GNSS L1
 MIMO1: MIMO1 Rx Path and n41 TRx
 MIMO2: MIMO2 Rx Path and n41 DRx and GNSS L5

mmWave connectors:
 Eight connectors — Up to four mmWave antenna modules (QTM525 or QTM527), two
connectors as a pair (H/V) for each. The EM9190 module does not have integrated antennas.
 Refer to
Table 3-1
QTM525 modules are equipped, integration sequence from QTM0 to QTM3 is recommended,
leave unused connectors NC (Contact Dejero Labs Inc as the RFC has to be updated to
reflect the number of QTMs). Note that for high-power usage, it's not recommended to leave
any QTM527 NC as it will violate 3GPP EIRP compliance for PC1.
